Module Description
This Actuator Driver module receives digital information from the CPU and generates four proportional actuator-driver signals. These signals are proportional and their maximum range is 0 to 25 mAdc or 0 to 200 mAdc. Figure 10-5 is a block diagram of the four-channel Actuator Driver module. The system writes output values to dual-port memory through the VME-bus interface.
The microcontroller scales the values using calibration constants stored in EEPROM, and schedules outputs to occur at the proper time. The microcontroller monitors the output voltage and current of each channel and alerts the system of any channel and load faults. The system can individually
disable the current drivers. If a fault is detected which prevents the module from operating, by either the microcontroller or the system, the FAULT LED will illuminate.
10.3.3—Installation
The modules slide into card guides in the control’s chassis and plug into the motherboard. The modules are held in place by two screws, one at the top and one at the bottom of the front panel. Also at the top and bottom of the module are two handles which, when toggled (pushed outward), move the modules out just far enough for the boards to disengage the motherboard connectors.
10.3.4—FTM Reference
See Chapter 13 for complete field wiring information for the Four Channel Actuator Module FTM. See Appendix A for part number cross reference for modules, FTMs, and cables.
10.3.5—Troubleshooting
Each I/O module has a red fault LED, which indicates the status of the module. This LED will help with troubleshooting if the module should have a problem. A solid red LED indicates that the actuator controller is not communicating with the CPU module. Flashing red LEDs indicate an internal problem with the module, and module replacement is recommended.
Module Description
Each Real Time SIO Module contains the circuitry for three RS-485 ports. Each port is designed to communicate with EM or GS/LQ Digital Actuator Drivers. For each port, one driver is allowed for every 5 ms. Each driver is identified by its address switches, which must match the driver number in the GAP application program. The RS-485 communications to the Universal Digital Drivers can be used for monitoring or control purposes.
