The pinout of this connector is as follows:

Fault Monitoring

The IntelliAmp’s internal Failure Relay is energised in normal operation (COM connected to NC). Power failure or a pre-defined fault condition causes the relay to release, when COM will be shorted to NO. External fault monitoring equipment can be connected to COM and either NO or NC as required, depending on whether the external system registers a fault condition as a short-circuit or an opencircuit. The relay contacts are fully floating (volt-free).

The fault conditions under which the IntelliAmp failure relay is de-energised are user-definable, and are loaded as part of the unit’s settings file with WinControl.

Status lED

Note that the front panel Status LED mimics the operation of the failure relay. The LED is green in normal operation, and goes red when a fault condition arises.

The diagram above illustrates how this connector may typically be wired.

The external fan control is not operational, the IntelliAmp is equipped with internal temperature-controlled fans.

Please note that Failure Relay and SPL/Temp sensor connectors are both of the same type, do NOT interchange!
