The "relays/controls" menu

"pump control N" (N = 1 or 2)
"reference"
Defines the level channel to which the pump control refers.
Selection:
• none (default)
• level 1
• level 2 (for instrument versions with 2 level inputs)
"number of pumps"
Defines the number of pumps participating in the pump control. At the end of the configuration
procedure a relay must be allocated to each of the pumps ("relay allocation" parameter set).
• Range of values : 1 ... 6 (depending on the number of relays)
•Default: 1
"standby pump"
(only for instruments with external limit switches)
Determines if one of the pumps is a standby pump.
Selection:
• no (default)
There is no standby pump.
• yes
The last of the pumps is a standby pump. It can not be configured individually. If a failure of one
of the other pumps is reported to the Prosonic S, the standby pump substitutes for this pump.
Example:
number of pumps: 5
standby pump: yes
=> pump control for pumps 1 to 4; pump 5 is the standby pump
"reset"
This parameter is used to restart the pump control (e.g. after a failed pump has been repaired).
!
Note!
The reset has the same effect as a disconnection of the supply voltage. It does not influence the
parametrization of the pump control.
Selection:
• no (default)
The pump control is not reset.
• yes
The pump control is reset.
