"pump M/control N" (M = 1 - 6, N = 1 or 2)
(Part 3: Parametrization of the associated switch inputs)
!
Note!
This parameter exists only for intruments with external limit switches.
"pump feedback"
Defines which digital input is used for pump feedback.
Selection:
• disabled (default)
no feedback
• ext. digin 1
terminals 71, 72, 73
• ext. digin 2
terminals 74, 75, 76
• ext. digin 3
terminals 77, 78, 79
• ext. digin 4
terminals 80, 81, 82
"feedback delay"
Defines in which time interval after a pump start a feedback is required.
Feedback messages after this time are ignored.
Default: 30 s
!
Note!
When setting the feedback delay, the startdelay of the relay (which is defined in the safety settings
menu) has to be taken into account. Depending on the number of connected pumps the feedback
delay must be at least "number of pumps x startdelay relay".
"feedback meaning"
Defines the meaning of the feedback signal.
Selection:
• pump start (default)
The feedback signals the start of the pump.
If no feedback is given within the feedback delay, the standby pump is started (if one has been
defined).
• pump failure
The feedback signals a failure of the pump. If a standby pump has been defined it is used to replace
the failed pump.
"
Caution!
If the connected pumps are shut down as a consequence of an error message, it is advisable for
security reasons to switch off the control unit Prosonic S as well.
