P937 General Control/Pump Relay Colour<br />
This parameter selects the colour that a pump relay should be when it is in<br />
its “ON” state. The default is 2 = green, but can be changed to ‘no colour’,<br />
red or yellow.<br />
P938 Control Relay Colour<br />
This parameter selects the colour that a control relay should be when it is in<br />
its “ON” state. The default is 2 = green, but can be changed to ‘no colour’,<br />
red or yellow.<br />
P939 Miscellaneous Relay Colour<br />
This parameter selects the colour that a miscellaneous relay should be when<br />
it is in its “ON” state. The default is 2 = green, but can be changed to ‘no<br />
colour’, red or yellow.<br />
All relays that are not programmed will show, ‘no colour’, i.e. they are off.<br />
Watchdog<br />
You can check how many times the unit has been switched on, and look at<br />
the date and time of the last ten starts. This can be useful if there have been<br />
power failures or if for any reason the <strong>FlowCERT</strong> LITE restarts due to a<br />
fault condition. The <strong>FlowCERT</strong> LITE can be backed up from a battery<br />
which automatically cuts in during power failure, battery backed up units<br />
will continue uninterrupted operation and therefore will not register a loss of<br />
mains power. If, however, the battery were to fail during a mains power<br />
interruption, a start up would be recorded once power has been restored.<br />
The following parameters can be accessed by directly entering the parameter<br />
number. To do this, enter the program mode and then type in the<br />
appropriate parameter number.<br />
P940 Number of Starts<br />
This parameter shows how many times the unit has been powered up.<br />
P941-P960 Start Date & Time<br />
Parameters P941 and P942 show the date and time that the unit was last<br />
started. There are ten start dates & times recorded, which are parameters<br />
P943 - P960. The first on the list are the most recent, and the last ones are<br />
the oldest. These are read only, and cannot be changed.<br />
