Step Parameter set or submenu Parameter Remarks see page
1 "relay/controls" menu 1. Select "pump control1" or "pump control 2".
2. Select "basic setup".
2 pump control N
(N = 1 or 2)
reference Select the level according to which the pumps are controlled. 99
number of pumps Select the number of pumps.
Note: A relay must be available for each pump.
99
standby pump
1)
Define, if one of the pumps is to be a standby pump. 99
reset Restarts an existing pump control; is not used during the parametrization. 99
3 pump control N
(N = 1 or 2)
function Select "limit parallel" or "limit simple". 100
load control Select the type of load control (only relevant for alternating pump control) 100
4 pump control N
(N = 1 or 2)
Select a pump.
(Each pump must be configured individually.)
5pump M control N
(M = 1 - 6)
(N = 1 or 2)
switch on point Define the switch on point for this pump. 101
switch off point Define the switch off point for this pump. 101
switch on delay Define the switch on delay for this pump. 101
alternate Select if the pump is to take part in the alternating pump control (Default:
no).
102
degree of use Define the desired degree of use (percentage) for this pump;
(only relevant for alternating pump control)
102
max. use time Define the maximum use time for this pump
(only relevant for alternating pump control with "load control" =
"starts+time")
102
crust reduction Define the inaccuracy of the switching points (to reduce crust formation). 102
6pump M control N
(M = 1 - 6)
(N = 1 or 2)
backlash interval Define the backlash interval. 103
backlash time Define the backlash time. 103
error handling Define the error handling. 103
7pump M control N
(M = 1 - 6)
(N = 1 or 2)
pump feedback Select the digital input used for pump feedback. 104
feedback delay Define the time interval in which a feedback is required. 104
feedback meaning Define the meaning of the pump feedback. 104
8 relay allocation Allocate a relay to the pump.
Note: By default, relay 1 is configured as alarm relay.
9relay N
(N = 1 - 6)
function Select "pump M/control N" 105
invert Select if the switching signal is inverted (default: no) 105
10 pump control N Select the next pump and continue with step 5 until all pumps have been
configured.
If all pumps are configured: Press to return to the "relay/controls" menu.
1) only for instruments with external limit switches; the stand-by pump always is the last of the M pumps.
