Remote Peak Shave or Area Protection Circuit
Illustration 1 g00828146
Energize the Q2 input in order to simulate a failure of the normal power source. This simulation will cause the generator to start. The switch will transfer the load to the emergency power source. If the emergency power source fails during the simulation, the transfer switch will transfer the load back to the normal power source.The Q2 input module requires an input of 24 DCV.Disable the Transfer of the Load to the EMERGENCY Position From a Remote Location.

If a voltage is applied to the Q3 input, the transfer switch will allow the load to be transferred to the emergency power source. No input on Q3 will disable a transfer to the emergency power source.Note: In order to enable the Q3 option, engage the Q3 jumper.The Q3 relay requires an input of 24 DCV.Disable the Transfer of the Load to the NORMAL Position From a Remote Location.

Energize the Q7 input in order to prevent transferring the load to the normal power source.The Q7 input module requires an input of 24 DCV.Load Shed

Energize the R15/R15D input in order to cause the unit to transfer the load out of the EMERGENCY position. This input can be used in order to prevent generator overload.On a CTS transfer switch, the R15 will transfer the unit to a normal power source that is dead.On a CTSD transfer switch, the R15D will transfer the unit to a neutral position. The unit will transfer the load to the normal power source if the normal power source is acceptable.The Q3 input is used to keep the unit from transferring back to the emergency power source.The R15/R15D relay requires an input of 24 DCV.
