English OPERATION AND FUNCTION
5.4.13. Switching service interval display on/off
To increase operational reliability of the unit,
aserviceintervalindicatorcanbeswitchedon.
Afterthesetintervalhasexpired,avisualsignalis
emitted by means of the yellow LED on the front.
No audible signal is emitted and the collective
fault contact is not activated! Time is only record-
ed continuously when mains voltage is present.
Counter reset must be carried out by Wilo Cus-
tomer Service.
The function and the desired interval can be
switchedon/offviaDIPswitch2,DIP4and5:
• DIP4and5"OFF":Serviceintervaloff(factory
setting)
• DIP4ON:¼yearserviceinterval
• DIP5ON:½yearserviceinterval
• DIP4and5"ON":1yearserviceinterval
5.4.14. Switching monitoring of operating parameters
on/off (version S only)
To increase the operational reliability of the unit,
the following operating parameters can be moni-
toredontheconnectedpumps:
• Connections/h
• Connections/d
• running time/h
After the factory-set parameters have been
exceeded,avisualsignalisemittedviatheyellow
LED on the front. No audible signal is emitted and
the collective fault contact is not activated!
Counter reset must be carried out by Wilo Cus-
tomer Service.
Monitoring can be switched on/off individually via
DIPswitch2,DIP1to3:
• DIP1:Connections/h
• DIP2:Connections/d
• DIP3:Runningtime/h
Allmonitoringisdeactivatedasafactorysetting
(DIPin"OFF"position).
5.4.15. Adjusting the follow-up time
Follow-uptimeisthetimebetweentheoat
switch"OFF"signalandthepumpbeingdeacti-
vated by the switchgear.
The follow-up time is continuously adjusted via
thepotentiometer.Settingrange:
• Standardversion:0...120s
• VersionS:0...30s
• "O"version:0...120s
5.4.16. Installing the rechargeable battery
Byinsertingarechargeablebattery,alarmsignals
will be emitted independent of the electricity
network on power failure. An audible, constant
tone will be emitted as an alarm.
1. Place the rechargeable battery in the holder. Pay
attention to the correct polarity.
2. Secure the rechargeable battery using the en-
closed cable tie
NOTE
• To ensure perfect operation, the rechargeable
battery must have been fully charged prior to
insertion or have been charged for 24 h in the
switchgear.
• The capacity of the rechargeable battery will fall
if temperatures drop. This reduces the running
time of the rechargeable battery.
6. Operation and function
This section contains all information on operating
the switchgear and how it functions.
POTENTIALLY fatal danger due to electrical
voltage!
