0 = No wire link applied to the input,
1 = Link applied to the input.
5.5. Initial Power ON
When the wiring and configuration is complete power can be applied to the unit. The power indicator on the front panel
will light up to indicate the unit is powered.
5.6. Status Indicators
5.6.1. Fault LED
On the front panel below the power LED there is a Fault LED which will illuminate whilst a fault is present. The
conditions which cause the unit to go into fault are:
-
A communication fault between MelCOMMS MINI and one or more MelcoBEMS MINI (A1M) units.
-
A fault code read from any MelcoBEMS MINI (A1M) unit which is not 8000 (8000 = OK).
5.6.2. Buzzer
The buzzer will activate at the same time as the Fault LED. However, the buzzer can be muted by pressing the 'Mute'
pushbutton. The buzzer will stay muted until a new fault is present after all faults have been cleared.
5.6.3. Relay Status LEDs
Inside the enclosure on the PCB there are four LEDs which provide the status of each of the four relays. When the LED
is OFF the relay is de-energised, when the LED is ON the relay is energised.
The LED labelled 'Relay 3' is for the Fault Relay and the LED labelled 'Relay 4' is for the High Temp Relay.
