PROTECTED AC OUTPUT MODULE WITH MONITOR INPUTS GEK-90757 GENERAL DESCRIPTION The Protected AC Output module consist of four isolated triac power switches and output monitoring circuitry for each. The module can be installed in either an Input/Output (I/O) Rack or a Model 60 Central Processor Unit (CPU). The module is used to switch user provided 115 Vac power sources to user loads in a programmable sequence. The power output to the user load is protected by monitoring circuitry which disables the output if a failure of the output triac occurs. The location of the failed circuit is reported to the CPU as an input signal. Loss of output because of a blown fuse or user input power loss is also reported to the CPU. The module uses both input and output I/O address locations to return monitor inputs and program outputs (Refer to Tables 2 and 3). The module may be used for many applications. Non-Programmable Monitoring: (Program Fault Monitor Jumper position l-2). The application is as a four-circuit four amp isolated output driver with blown fuse feedback and triac failure feedback to the CPU. Part of the Triac Failure Monitor circuit is an automatic circuit which detects a voltage output when there should not be a voltage output and blows the fuse on that output. The Module will then notify the CPU that a failure exist. This type of operation exist when the Program Fault Monitor Jumper is in the normal monitor enabled position I-2. It is the option of the user to use or not to use the monitor feedback fault signals in his ladder diagram program. Programmble Fault Monitoring: (Program Fault Monitor Jumper Position 2-3). A very useful application is with the program fault monitor jumper in the programmable monitor position (2-3). In this application the module is also used as a four-circuit four AMP isolated output driver with blown fuse feedback to the CPU. The basic difference is, should a triac circuit fault occur, the monitoring of the output and the subsequent forced blowing of the fuse is under the direct control of the User Ladder Diagram Program contained in the CPU. If a monitor input (M)to a particular circuit on this module is programmed in the user ladder diagram to be in the fault monitor state and an output triac fault should occur, then, the fuse for that circuit will automatically be blown and feedback given to the CPU of the circuit malfunction. If that circuit is not programmed by the user ladder diagram to be in the fault monitor state and an output triac fault should occur, there will be no feedback of fault and the fuse will not be blown to disable the circuit. This programmability of the fault monitor input allows standby redundant wiring of two drivers to the same user load. This monitor input control allows ladder diagram programming of an automatic switch-over from a primary driver to a secondary driver should a blown fuse or triac output fault occur in a circuit that is driving a critical load. This allows the control to continue operating and delays shutdown of the control for repair until after a critical operation or batch process is completed. This is not to be implied that this operation is FAIL SAFE , bumpless transfer, or repairable while the control is in operation. It will also not protect against an external load malfunction or fault. This application is discussed in more detail in the Installation section, paragraph six.

The Protected AC Output may be installed in an I/O rack or the I/O section of the Model 60 CPU rack. Before installing the module, the Dual-In-line Package (DIP) switches on the rack backplane should be set to establish the correct module address location. A group of eight consecutive I/O points are required to communicate with both the Output Status Table and the corresponding points on the Input Status Table. The DIP switch setting is done in the same fashion as for an eight point input or output board. For further information on the I/O Dip Switch Setting refer to the Installation and Maintenance Manual, GEK-25361. Tables 2 and 3 show the output and input table status displays. 2. The \"Program Fault Monitor\" jumper position should be verified. Refer to Sections 4.4 and 6.1 below for setting. 3. It is recommend that one use the extraction/insertion tool furnished with the CPU to remove or install the circuit board. With the board in place in the rack, the faceplate should be slipped over the circuit board so that the terminals near the bottom of each are mated. Then secure the faceplate to the rack using the thumbscrews at top and bottom. SHARED BY ALL OUTPUTS. 1-2 MONITOR ENABLED 2-3 MONITOR PROGRAMMED FROM CPU FROM OTHER CIRCUITS Pc SO 83-0101 N. INDICATOR (ONE PER BOARD) FIGURE 3. BLOCK DIAGRAM AC OUTPUT WITH FAULT DETECTION FOUR DRIVERS PER MODULE 4. A simplified module block diagram is shown in Figure 3. The following signals shown on the block diagram are defined as follows: 4.1 OUT: This CPU signal turns on the AC output at the next zero crossing of the AC line. 4.2 BLOWN FUSE (BF) Output Signal: This input to the CPU is turned on when the output is called for and no load voltage is detected. This detects either a blown fuse or a loss of the user AC load power source. This signal is not latched and is independent of the monitor enable signal. Note that the module faceplate BF light indicates open fuse only, and relies on user AC input power, applied to the faceplate (H) terminal, to light. 4.3 Fault (FLT) Output Signal: The fault monitor compares the actual module output voltage to the CPU \"OUT\" command or status. If voltage is detected across the output when the CPU \"OUT\" instruction is in the \"OFF\" state, and the monitor is enabled, the FLT output to the CPU is turned ON. This signal is also used to turn on a \"CROWBAR\" triac to blow the fuse, and to light a shared module front indicator light. The FLT signal to the CPU and indicator is latched, and cannot be reset except by removing rack logic power. Ref. PC-S6-83-0161 5 Protected AC Output Module With Monitor Inputs GEK-90757 4.4 Monitor (M) Input Signal: When the program fault monitor jumper is in the ENABLED position, (l-2). the monitor (M) output table states from the CPU are ignored by the module and these (M) outputs may be used for other purposes, One of these uses might be as internal ladder diagram coils. When the jumper is in the PROGRAM FAULT MONITOR position (2-3) the monitor (M) output table states from the CPU are read into the fault monitor circuit of the module. This mode of operation is used when it is desired to switch between two output circuits to drive a single load. This allows ladder diagram programming to control the change to backup driver operation when a problem is detected in the primary driver. This backup configuration wiring is shown in Figure 5. The backup driver operation is described in more detail in Section 6. Note that the jumper and M signals affect only the FAULT MONITOR circuit operation and crowbar triac operation after the FLT condition exists. 4.5 Table 2 shows the interface signals from the CPU to the module as they appear in the CPU output tables. Table 3 shows the interface signals from the module to the CPU as they appear in the CPU input tables. TABLE 2.

Typical customer connections are shown in Figure 4. 115VAC 15 VAC OUTP?JT SWlrCi- lNG DEY!CE AC POWER SOURCE USER LOAD Voltages from user field devices could be present on the faceplate terminals, even if the power supply in the I/O rack is off. Care should be taken when handling the faceplate of this module or any wires connected to it. Connect only loads to the output terminals (01, 02, 03 and 04). Never connect a user power source to the output terminals (01, 02, 03, and 04) for any reason. If a power source is connected to the output terminals damage to the module will occur. In this instance the monitor will mistake this power source connection for a shorted output triac and attempt to blow the internal fuse to prevent and incorrect output. In attempting to blow the internal fuse the crowbar triac in this module will place a short on the incorrectly connected user power source. This will result in the module crowbar circuit becoming overheated because of excessive current and destroying itself. FIGURE 4. TYPICAL CUSTOMER CONNECTIONS 6. A TYPICAL CONNECTION for a STANDBY REDUNDANCY circuit is shown in Figure 5. In a standby redundant circuit, one output drives the load in the normal fashion while the standby output is forced off by CPU ladder diagram. If a fault is detected in the main driver and the proper program is contained within the user ladder diagram, then control is switched to the standby driver so operation can continue. This redundant mode is applicable to operations where it is desirable to delay shutdown for repairs until after a critical operation or batch process is completed. It is not to be implied that the operation is fail safe, bumpless transfer, or that the system is repairable while in operation. 6.1 If a standby redundancy system of two drivers connected to the same user load is used as shown in Figure 5, several precautions must be observed. The output drivers may be in the same module or different modules of the same type, The user s power source to the two drivers may be the same or different sources. If separate sources are used, one side of the line must be common and the AC phase must be the same to prevent over voltaging whichever driver is off. The program fault monitor jumper should be set for Programmable Monitor position 2-3 on each driver module. The normal output driver being used should have the CPU output M signal set high or 1 while the standby output driver should have the CPU output M signal set low or 0. If a BF (Blown Fuse or loss of user power to the H terminal) fault is detected on the normal output driver the BF signal will be returned to the CPU as an input. The user ladder diagram program should then acknowledge this signal by turning off the Output Signal to this normal output circuit, turning off the monitor input signal to this normal output circuit, turning on the CPU output signal to the standby driver, turning on the monitor input signal to the standby driver, and turning on an alarm output to acknowledge to the user that a blown fuse has been detected in the normal output driver and a transition has been made to the standby driver. Ref. PC-S6-83-0164 Protected AC Output Module With Monitor Inputs GEK-90757 If an FLT (output triac or output circuit) fault is detected on the normal output driver the FLT signal will be latched into memory within the Output Driver module, returned to the CPU as an input, and used within the normal Output Driver module to turn on the crowbar triac and blow the output driver fuse. This blowing of the fuse will prevent wrong outputs from this driver. The user ladder diagram program should acknowledge this FLT input signal by first watching for the corresponding BF (Blown Fuse) input signal. When the BF signal is received the ladder diagram program should then turn off the monitor input signal to this normal output circuit. The CPU output signal should then be switched to control the standby output driver. The ladder diagram program should at this time enable the MONITOR input signal to the standby output driver. Finally the user ladder diagram program should signal that the transition has been made by turning on an alarm output to acknowledge that an output FLT signal has been received, acted upon, and transition has been made to the standby driver. The only way to reset this latched in FLT (output triac fault) signal from the driver module to the CPU is to remove and reapply AC power from the rack containing the driver module. Using this standby redundancy type of output operation is not to be implied that the operation is fail safe, bumpless transfer, or that the system is repairable while in operation. This type of operation is only used where it is desirable to delay shutdown until after a critical or batch process is complete. 6.2 Attention is called to the warning note and caution note that is part of Figure 4. If separate power sources are used care should be taken to insure that one side of the line is common, and the AC phase must be the same to prevent over voltaging whichever driver is off. Also steps should be taken in the user ladder diagram program to prevent both outputs from being programmed on at the same time. This could cause circulating currents between the sources through the drivers and cause a fuse to blow. The program fault monitor jumper should be in Position 2-3 on both the normal and the standby output driver modules.
