FORM 50.40-OM2 There can be electrical circuitry that presents an electrocution hazard. Be sure that the sources of all power supplies have been properly isolated and secured before attempting any service related activities. External wiring, unless specified as an optional connection in the manufacturer’s product line, is not to be connected inside the OptiView Remote Control Center cabinet.
Installation equipment in the plant on the same circuits will ground themselves to the ground stake causing large ground flow at the electronic equipment. LD06728 FIG 4 – GROUNDING Wiring Practices (Figure 5) LD06727 FIG. 3 – CONTROL INSTALLATION Grounding Grounding is the most important factor for successful operation. Electronic equipment reacts to very small currents and must have a good ground in order to operate properly.
FORM 50.40-OM2 Never run refrigerant, water or brine tubing inside an electronic control panel. A leak could damage or in some cases totally destroy the electronics. If the electronic control panel has a starter built into the same panel, be sure to run the higher voltage wires where indicated by the manufacturer. EMI from the wires can interfere with the electronics if run too close to the circuitry. LD06738 FIG.

Service MICROBOARD (REFER TO FIG. 31 - 36) The Microboard contains the operating software (Program), microprocessor (Micro), and supporting circuits for the Micro. The Program is a set of instructions to control remote chillers and the display. It also contains the Display messages and screens. It is stored in a memory device called a flash memory card. This is a type of nonvolatile memory that can be read from or written to, but requires the locations to be erased before they are written to.
FORM 50.40-OM2 The DRAM (dynamic random access memory) is a non battery-backed memory device. The Micro stores data here temporarily for further processing. Data in this device is lost during power failures. DRAM differs from RAM in that DRAM must be periodically refreshed in circuit. The BIOS EPROM (basic input/output system erasable programmable read only memory) is a memory device that contains the bootstrap or power-up program. It is located in socket location U45. This EPROM is replaceable.
Service The BRAM (battery backed random access memory) is a memory device that contains a battery that preserves the data during power failures. It is a replaceable part. Refer to the YORK Renewal Parts List. It is located in socket location U52. The Micro stores the setpoints programmed by the Operator or Service Technician, History Data and other data that requires preservation, in this device. Also, the day of week, time of day and calendar date time-keeping are done here.
FORM 50.40-OM2 COM 1 is connected directly to the Micro. COM 2 through 5 are connected directly to the UART (Universal Asynchronous Receive Transmit). The UART converts the parallel data to serial form for transmission to the peripheral device and converts the incoming serial data to parallel form for use by the Micro. It also generates and processes control signals for the Modem communications (DTR, CTS, DSR, RTS).
Service Program Jumper JP5) to high voltage AC (500 to 1500VAC). This high voltage AC is applied to the lamp to cause it to illuminate. The Backlight is turned on and off with the “Enable Backlight” (J6-5) signal. The position of Program Jumper JP4 determines whether this is a +12VDC or +5VDC signal. In some displays, the Backlight turns on when this signal transitions from low to high; others turn on when it transitions from high to low.

FORM 50.40-OM2 SERIAL INPUTS / OUTPUTS TESTS 00530VIPC FIG. 52 This diagnostic is used to verify correct operation of the Serial Data Ports. There is a test for each of the five Serial Data Ports. Each RS-232 port (COM 1, 2 and 4b) is tested by transmitting serial test data from outputs to inputs of each port. Both the transmit and receive functions as well as the control lines are tested. The RS-485 ports (COM 3 and 4a) are tested by transmitting serial test data from one RS-485 port to another.
Service displayed, indicating the Serial Port is defective. A FAIL result would be indicative of a defective Microboard. The following is a description of each test. COM 1 – Two tests are performed. Test data is sent from TX (J2-4) to RX (J2-3) at 9600 Baud and DTR (J2-5) is set to a Logic High level and read at DSR (J2-2). If any test fails, COM 1 tests are terminated. COM 2 – Three tests are performed. Test data is sent from TX (J13-5) to RX (J13-3) at 19200 Baud.
