When specified for use with a CTGD Series delayed transition switch, the control panel also includes the following:
Time Delay for Engine Cool Down: Allows engine to run unloaded after switch retransfer to normal; standard setting 5 minutes, adjustable 0-60 minutes
Time Delay on Transfer to Emergency: To delay transfer to emergency after verifying emergency source available; standard setting 1 second, adjustable 0-5 minutes
Timer and voltage/frequency settings adjustable without disconnection from power sources
Built-in diagnostics with LCD display for immediate troubleshooting
LED/LCD indicators for ease of viewing and long life
Nonvolatile memory (exerciser battery backup not required for standard operation)
Processor and digital circuitry isolated from line voltage
Inputs opto-isolated for high electrical immunity to transients and noise
Communications header for network interface
Plant Exerciser, clock type (load/no load): Allows the generator to start and run unloaded or to simulate a power failure, start generator and run under load (7-14-28-365 days, user selectable)
Space heater and thermostat
Network communications interface card (LonWorks / ModBus)
Maintained Test Switch
Maintained Test Switch w/Keypad
Service entrance configuration
Auxiliary Contact, operates on Source 1 line failure
Auxiliary Contact, operates on Source 2 availability
Auxiliary Contacts: Closed when the transfer switch is in Source 2 position
Auxiliary Contacts: Closed when the transfer switch is in Source 1 position
Disconnect Switch: Permits transfer in “AUTO” position and inhibits transfer in “INHIBIT” position. (Standard 800A and above)
Elevator Pre-Signal Auxiliary Contacts: Open 0-60 seconds prior to transfer to either direction, re-closes after transfer
Universal Motor Load Disconnect Circuit: Auxiliary Contact opens 0-60 seconds prior to transfer in either direction, re-closes after transfer. Can be configured by end user for Pre-transfer, Post-transfer, or both.
Voltage Imbalance Monitor (Three Phase)
Lockable, see-through cover for ATS controller
Power Measurement Meters
Note:For applications requiring additional options or other configurations, see the CTS Series fully configurable transfer switch.
