Pump Control Default Program
Changing the application to Pump Control loads this default program into memory.
Pr.2.0 Empty Distance
6.000m
Start 2
Pr.8.2.1.1
2.000m
Pr.4.0 Blanking 0.500m
Pr.3.0 Operational
Span
5.500m
Stop 1
Pr.8.1.1.2

Stop 2
Pr.8.2.1.2
0.500m
Start 1
Pr.8.1.1.1
1.000m
This default program is created to do the following:
2 pump control, pump down in a wet-well, duty-assist operation.
Alternate pump duty to reduce wear.
4-20mA to remote indicator.
Loss-of-Echo indication to telemetry.
Display actual level in metres.
This program can be easily modified to suit the required application. You should delete from
this program any unwanted entries (e.g. 9.2.1 Duty assist).
Parameter Default Description
number Setting
2.0 Empty Distance = 6.000 Distance from transducer to zero level.
3.0 Operational Span = 5.500 The span, over which measurement is required.
4.0 Blanking = 0.500 Blanking zone into which level should not rise.
5.0 RateOfChange = 1.000 The maximum rate of change of liquid level in
metres/minute.
8.1 Rly1 Options = 8.1.2 Relay 1 Norm-DeEnergised Relay 1 control on level (normally de-
energised)
8.1.1.1 Relay 1 Set = 1.0 Relay 1 energises at 1.0m to turn pump 1 on.
8.1.1.2 Relay 1 Reset = 0.5 Relay 1 de-energises at 0.5m to turn pump off.
8.2 Rly2 Options = 8.2.2 Relay 2 Norm-DeEnergised Relay 2 to control on level (normally de-
energised)
8.2.1.1 Relay 2 Set = 2.0 Relay 2 energises at 2m to turn pump 2 on.
8.2.1.2 Relay 2 Reset = 0.5 Relay 2 de-energises at 0.5m to turn pump 2
off.
8.3 Rly3 Options = 8.3.4 Relay 3 L.O.E. Alarm Relay 3 (L.O.E. Alarm – de-energises relay)
9.1 Pump Sequence = 9.1.2 Alternate pumps 1 & 2 Alternate pumps 1 & 2
9.2 Duty Standby = 9.2.1 Duty Assist Duty assist operation.
10.1 Relay 1 = 10.1.2 Relay 1 De-Energise Pump 1 de-energise on failsafe.
10.2 Relay 2 = 10.2.2 Relay 2 De-Energise Pump 2 de-energise on failsafe.
10.4 Fail Time = 30 Failsafe time in seconds
10.5 mA Fail = 10.5.2 Analogue High Analogue output goes high on failsafe.
11.1 Analog O/P = 11.1.1 Output 4–20mA 4-20mA output fixed to span (Pr.4).
To simulate the program go to 12.5.2 yes then press ENT again.
