Parameters 265
79.02 Stopping mode Selects whether the pumps are stopped simultaneously or
individually.
Stable level When the start level of a pump (parameters 79.06 Start 1
level…79.13 Start 8 level) is reached, the master drive waits
for the level delay (parameter 79.16 Start stop delay) to
elapse, then stops the pump.
0
Common stop All the pumps running will continue to run until the stop level
(parameter 79.05 Stop level) is reached. All pumps will then
be stopped one by one at intervals defined by parameter
79.16 Start stop delay.
1
79.03 Low level Defines the low level for level control.
In emptying mode, when the measured level falls below the
low level, all pumps stop (if not stopped already).
In filling mode, when the measured level falls below the low
level, all pumps start running at the speed defined by
parameter 79.19 High speed.
See the diagrams at parameter 79.01 Level mode.
0.00 … 32768.00% Low level. TBA
79.04 Low switch Selects a digital source that is used to determine that the
liquid level in the container has fallen very low. When the
source becomes active (1), an alarm, LC TANK EMPTY is
given. The alarm is cleared when the source switches off.
Not used No low switch used. 0

DI3 Digital input DI3 (as indicated by 02.01 DI status, bit 2). 1073873409
DI4 Digital input DI4 (as indicated by 02.01 DI status, bit 3). 1073938945
DI5 Digital input DI5 (as indicated by 02.01 DI status, bit 4). 1074004481

109).

79.05 Stop level Defines the stop level for the pump station.
If parameter 79.02 Stopping mode is set to Stable level,
pumps 3 and 2, for example, are stopped when 79.08 Start 3
level and 79.07 Start 2 level are reached respectively; pump
1 is stopped at the stop level.
If parameter 79.02 Stopping mode is set to Common stop, all
pumps will continue to run until the stop level is reached.
See the diagrams at parameter 79.01 Level mode.
0.00 … 32768.00% Stop level. TBA
79.06 Start 1 level Defines the start level for pump 1. See the diagrams at
parameter 79.01 Level mode.
0.00 … 32768.00% Start level for pump 1. TBA
79.07 Start 2 level Defines the start level for pump 2. This is also the stop level
for the pump unless Common stop is selected at parameter
79.02 Stopping mode. See the diagrams at parameter 79.01
Level mode.
0.00 … 32768.00% Start level for pump 2. TBA
