Settings
'Max. on time:'
2 potmeters for each relay output are placed in the front panel.
The setting of the potmeters determines the maximum
continuous activation time for the belonging relay:
Setting of activation delay for
the alarm relay.
(Approx. 0,2 to 30 min.)
Setting of the maximum
continuous running time for
the pump for each start.
(Approx. 0,1 to 8 min.)
'Delay:'
If the level for any reason should reach the alarm electrode, or if
one of the pumps has been stopped because of runout of the
preset maximum continuous running time, the caused alarm will
be delayed for a period set by means of this potmeter.
An alarm will also occur if the level does not reach the stop
electrode within a fixed running period.
'Alternation:'
Relay no. 1 will always be activated first, if the alternation switch
is set to 'OFF'. Thereafter, relay no. 2 is activated if the level
continues to rise
If the switch is set to 'ON', ConTroller 712 will alternate the two
relay outputs so that they will be leading every second time and
thus distribute the service hours equally between the two
pumps.
Maintenance
ConTroller 712 requires no particular maintenance.
The electrodes should be cleaned periodically.
