Starter Solid State - RTHD Only CH530 provides an interface with Non-Communicating Solid State Starter. The following points of interface are provided. Start contact closure output: This contact closure output will be closed when the compressor motor is to run and opened when the compressor motor is not to run. This output will be latched to prevent chatter of this command to the starter Up To Speed contact closure input: This contact closure input is closed when the solid state starter has started and accelerated the compressor motor. Failure of this input to close within the maximum acceleration time will cause the "Motor Failed to Accelerate" diagnostic to be called out. Starter Fault contact closure input: This high voltage binary input will be open when the solid state starter system is not powered and when the solid state starter has an active fault. It will be high voltage (115 VAC) during normal operation of the solid state starter. This input shall be ignored for five seconds following power-up. After the first five seconds, if this input voltage is high, a Starter Fault diagnostic shall be called out. The sequence of a Solid State Start is shown in Figure 29 Refer to RTHD-SVD01A-EN for IT Solid State Starter Troubleshooting. Refer to RTHD-SVD02A-EN for RediStart Solid State Starter Troubleshooting. RTHD Sequence of Operation: Starting Non-Communicating Solid State Starter Waiting To Start Check for At Speed Input Opened (1 Second) Energize Stop and Start Relays Confirm Individual Phase Currents are > 10% RLA within 2.6 seconds Accelerating Compressor (6 to 64 Seconds (Default 7 sec)) Starting Compressor Run Command to Starter Module Figure 29.RTHD Sequence of Operation Solid State Start Confirm At Speed Input within Maximum Acceleration Timer (Default 7 seconds) Running Running RLC-SVD05A-EN 43
