9.3.4 Buttons on pump
The operating buttons and on the control panel can be set
to these values:
•
Active
• Not active.
When set to Not active (locked), the buttons do not function. Set
the buttons to Not active if the pump should be controlled via an
external control system.
9.3.5 Pump number
A number between 1 and 64 can be allocated to the pump. In the
case of bus communication, a number must be allocated to each
pump.
9.3.6 Digital input
The digital input of the pump (terminal 1, figures 4 , 8 and 14 ) can
be set to different functions.
Select one of the following functions:
•
Min. (min. curve)
• Max. (max. curve).
The selected function is activated by closing the contact between
terminals 1 and 9 (figures
4 , 8 and 14 ).
See also section 12.2 Digital input .
Min.:
When the input is activated, the pump is operating according to
the min. curve.
Max.:
When the input is activated, the pump is operating according to
the max. curve.
9.3.7 Motor bearing monitoring (only three-phase pumps)
The motor bearing monitoring function can be set to these values:
•
Active
• Not active.
When the function is set to Active, a counter in the controller will
start counting the mileage of the bearings. See section
9.2.7 Lubrication status of motor bearings (only 11-22 kW) .
9.3.8 Confirming relubrication/replacement of motor
bearings (only three-phase pumps)
This function can be set to these values:
• Relubricated (only 11-22 kW)
• Replaced
•
Nothing done .
When the bearing monitoring function is Active, the controller will
give a warning indication when the motor bearings are due to be
relubricated or replaced. See section
9.1.3 Fault indications .
When the motor bearings have been relubricated or replaced,
confirm this action in the above display by pressing [OK].
9.3.9 Standstill heating (only three-phase pumps)
The standstill heating function can be set to these values:
• Active
•
Not active .
When the function is set to Active, a low voltage will be applied to
the motor windings. The applied voltage will ensure that sufficient
heat is generated to avoid condensation in the motor.

Note
Fault and Alarm cover faults resulting in Alarm.
Warning covers faults resulting in Warning.
Relubricate covers only that one individual event. For
distinction between alarm and warning, see section
9.1.3 Fault indications .
Note
The counter will continue counting even if the
function is switched to Not active, but a warning will
not be given when it is time for relubrication.
When the function is switched to Active again, the
accumulated mileage will again be used to calculate
the relubrication time.
Note
Relubricated cannot be selected for a period of time
after confirming relubrication.
