How to Lockout a Compressor or Circuit?
Resolution:
RTAC Compressor or Circuit Lockout information:
Circuit Lockout - Circuit #1 and Circuit #2
- Using the TechView or KestrelView service tool, navigate to the Compressor Service View; choose the appropriate circuit control block (Circuit 1 Control or Circuit 2 Control); then select the button and change between Unlocked and Locked as needed.
- At the Local display - DynaView, select the Settings Tab. Tab down to Front Panel Circuit Lockout; choose the appropriate circuit and change between Not Locked Out and Locked Out.
Compressor Lockout - Compressor 1A, Compressor 1B, Compressor 2A, Compressor 2B
- Using the TechView or KestrelView service tool, navigate to the Compressor Service View; choose the appropriate compressor control block (Compressor 1A Control, Compressor 1B Control, Compressor 2A Control, Compressor 2B Control); then select the button and change between Unlocked and Locked as needed.
External Circuit Lockout - Circuit #1 and Circuit #2
- CH530 provides auxiliary control of a customer specified or installed contact closure, for individual operation of either Circuit #1 or #2. If the contact is closed, the refrigerant circuit will not operate.
- Upon contact opening, the refrigerant circuit will run normally. This feature is used to restrict total chiller operation, e.g. during emergency generator operations.
- Connections to the External Circuit Lockout LLID (1U5) are shown in the field diagrams that are shipped with the unit.
- These customer-supplied contact closures must be compatible with 24 VDC, 12 mA resistive load. Silver or gold plated contacts are recommended.
