English COMMISSIONING
DANGER due to explosive atmosphere!
If the switchgear or the connected pump
and signal transmitter are used in potential-
ly explosive areas, there is adanger of fatal
injuries from explosions! Theswitchgear and
connected pump and signal transmitter must
always be used outside of potentially explo-
sive areas.
7.3. Activating the switchgear
POTENTIALLY fatal danger due to electrical
voltage!
All settings need to be made on the switch-
gear components. There is arisk of fatal
electric shocks occurring when performing
work on the open switchgear. Allwork must
be carried out by aqualied electrician.
NOTE
Followingapowersupplyinterruption,the
switchgear will automatically start up in the last
operating mode set!
The following points must be checked before
activation:
• Check the installation.
• All terminals must be retightened.
• DIPswitches1and2correctlyset:
• Motor protection (DIP switch 1, DIP 1-5)
• Pump kick (DIP switch 1, DIP 6)
• Buzzer (DIP switch 1, DIP 7)
• Mainsvoltageselection(DIPswitch2,DIP1:
standardversionand"O"versiononly)
• Pumps activated (DIP switch 2, DIP 6 and 7)
• Follow-up time
If corrections are necessary, proceed as in the
section"Electricalconnection".
1. Turn main switch to ON position. On switchgears
withaplug,inserttheplugintothecorrespond-
ing socket.
2. AllLEDslightupfor2sec.
3. The switchgear is ready for operation.
• The"on"LEDlightsupconstantly.
• The"auto"LEDashes:Theswitchgearisin
stand-by mode, automatic mode is off.
• The"auto"LEDlightsup:Theswitchgearisactive,
automaticmodeison.Tosettheswitchgearto
stand-by mode, press the Stop button.
NOTE
If an audible signal is sounded after activation
andallLEDsashanti-clockwiseinturn(inlight
sequence),thereisaphasefaultinthemains
connection. Follow the instructions under “Ro-
tationcontrol"forthis.
7.4. Rotation control of connected three-phase AC
motors
Inthefactory,aswitchgearforaclockwise
rotatingeldischeckedforcorrectdirectionof
rotation and set.
Observe the wire designations on the wiring
diagram when connecting the switchgear and the
connected pumps.
7.4.1. Checking the direction of rotation
The rotation control of the connected pump can
beperformedusingabrieftestrun,max.2min-
utes.
1. Pressthe"Manual"buttononthecontrolpanel
for the relevant pump.
2. The pump operates as long as the button is held
down.
BEWARE of damage to the pump
A test run of the connected pump should only
be performed under the permissible operating
conditions. Forthis, observe the installation
and operating instructions for the pump and
ensure that the required operating conditions
are complied with.
7.4.2. If the direction of rotation is not correct
After activation, an audible signal sounds and all
LEDs ash in turn anti-clockwise:
The switchgear is incorrectly connected and the
connected pump is not operating correctly.
2 phases/conductors of the power supply on
mains side to the switchgear need to be swapped
over.
Pump running incorrectly:
Connection of the switchgear is correct. Con-
nection of the pump is incorrect. 2 phases of the
mains supply to the pump supply line need to be
swapped.
7.5. Activating automatic mode on the unit
Before automatic mode is switched on, check the
settings for the switching level and follow-up
time.
If all settings have been checked, you can switch
the unit on.
1. Pressthe"auto"buttononthecontrolpanel.
2. The"auto"LEDlightsupandtheunitnowruns
inautomaticmode.Assoonastheoatswitch-
esprovideacorrespondingsignal,thepumpis
activated
• "Base-loadpumpON"level:Iftheswitch-onlevel
isreached,pump1switchesonandthe"Pump
operation"LEDlightsuppermanently.
• "Peak-loadpumpON"level:Iftheswitch-onlevel
isreached,pump2switchesonandthe"Pump
operation"LEDlightsuppermanently.
• "Peak-loadpumpOFF"level:Iftheofflevelis
reached, the peak-load pump is switched off im-
mediately.The"Pumpoperation"LEDgoesout.
• "Base-loadpumpOFF"level:Iftheofflevelis
reached, the follow-up time set is active. During
thefollow-uptime,the"Pumpoperation"LED
ashes.Oncethefollow-uptimehasexpired,
thebase-loadpumpswitchesoffandthe"Pump
operation"LEDgoesout.
