LED Colour
Each relay has an associated LED, located on the unit’s front panel, which
indicates the status of the relay. By default the LED of any relay that has
been programmed but is in its “OFF” state will be illuminated ‘yellow’.
When “ON” alarm relays will cause the LED to illuminate Red and pump,
control and miscellaneous relays will cause the LED to illuminate green.
LED’s of any relays that have not been programmed will not be illuminated.
Customised settings for the colour of LED’s can be achieved by using the
following parameters.
P935 Off Relay Colour
This parameter selects the colour that a programmed relay should be when
it is in its “OFF” state. The default is 3 = yellow, but can be changed to ‘no
colour’, red or green.
P936 Alarm Relay Colour
This parameter selects the colour that an alarm relay should be when it is in
its “ON” state. The default is 1 = red, but can be changed to ‘no colour’,
green or yellow.
P937 Pump Relay Colour
This parameter selects the colour that a pump relay should be when it is in
its “ON” state. The default is 2 = green, but can be changed to ‘no colour’,
red or yellow.
P938 Control Relay Colour
This parameter selects the colour that a control relay should be when it is in
its “ON” state. The default is 2 = green, but can be changed to ‘no colour’,
red or yellow.
P939 Miscellaneous Relay Colour
This parameter selects the colour that a miscellaneous relay should be when
it is in its “ON” state. The default is 2 = green, but can be changed to ‘no
colour’, red or yellow.
All relays that are not programmed will show, ‘no colour’, i.e. they are off.
