Testing Calibration and Relays

Entek IRD 6687 Protection Monitor

The following table gives you example settings, inputs, and readings for an example
configuration.

Alarm Relay Test

The following steps show you how to test the monitor alarm relays. Most of the relays
reflect the alarm state (Alert or Danger) of an input channel. There is also a System OK
relay that responds to either channel 1 or channel 2 transducer fault, monitor system failure,
or loss of power. For the steps to test the System OK relay, see “Calibration and System OK
Relay Test” on page 28.

The HI alarm setpoints go into alarm when the input value goes above the alarm level. The
LO alarm setpoints go into alarm when the input value goes below the alarm level.

Remember that the 6687 has both LO and HI alarms. You should test both sets of alarms for
each channel if you are using them.

Note: If the LATCHED option is set to YES, you may have to manually reset the relays by

pressing the RES button on the front panel of the monitor. The LATCHED option is on the
RELAYS submenu (page 22).

The relay contacts on the backplane of the 6687 are:
