Operation And Function; Controls - Wilo Control MS-L 2x4kW Notice De Montage Et De Mise En Service

English
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 float
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

OPERATION AND FUNCTION

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!
There is a risk of fatal electric shocks oc-
curring when performing work on the open
switchgear. All work on individual com-
ponents must be performed by a qualified
electrician.
NOTE
Following a power supply interruption, the
switchgear will automatically start up in the last
operating mode set!

6.1. Controls

The switchgear is operated on the side control
panel via 5 buttons. The current operating state is
indicated via 11 LEDs on the front side.
6.1.1. Main switch (standard version only)
Disconnection from the mains is via a main switch
on the standard version.
Position "0" = switchgear OFF
Position "1" = switchgear ON
NOTE
The main switch can be secured against unau-
thorised activation/deactivation using a lock!
6.1.2. Buttons
Manual mode
P By pressing this button for the relevant pump
1
(pump 1 = P1, pump 2 = P2), the pump is switched
on independently of the level control signal.
P
2
The pump operates as long as the button is held
down. This function is intended for test mode.
Automatic mode
By pressing this button, automatic mode is activat-
ed. The pumps are activated depending on the level
control signal. When the pumps are deactivated,
the pump follow-up time is taken into account.
Stop
By pressing this button, automatic mode is deacti-
vated and the switchgear is set to stand-by mode.
The pumps are not controlled dependent on the
level.
