5.3.7 Power supply network
Use a three-wire electric cable (1 phase + neutral + earth) to
connect the single-phase network to terminals 2 and 6 of the main
isolating switch (See FIG. 2 - ref. 5).
Use a four-wire electric cable (3 phases + earth) to connect the
three-phase network to terminals 2, 4 and 6 of the main isolating swit-
ch (See FIG. 2 - ref. 5).
REMEMBER TO CONNECT THE EARTH.
Check the cable-glands (See FIG. 2 Ref. 11) are
CAUTION
tight enough to hold the cables properly and that
there is maximum tightness.
6. STARTING UP
6.1 Adjustments and checks
6.1.1 Thermal protection (See FIG. 2 - ref. 4)
Adjust the thermal relays according to the current given on the
pump motors, and adjust the value if necessary.
6.1.2 Rotary direction (three-phase version only)
- Connect the pumps as given in paragraph 5-3-2.
- Connect the network as given in paragraph 5-3-7.
- Shut the cover of the box.
- Set the rotary selector (See FIG. 3 - ref. 1) to P1.
- Set the main isolating switch (See FIG. 1 - ref. 2) to position 1, then to
0.
- Check the rotary direction during the off phase.
- If the direction is reversed, cross two phase wires from the pump sup-
ply cable to the motor terminal strip.
- Repeat for pump 2. For this, set the selector (See FIG. 3 - ref. 1) to P2.
6.2 Operating choice
Select by rotating the selector (See FIG. 3 - ref. 1) until the desired
mode (See FIG. 3 - ref. 2). has been obtained. The selector is acces-
sed by opening the front window (See FIG. 1 - ref. 1).
Order for changing the operating mode from the "0" position of the
selector :
"0" "P1" "P2"
NB : The module is delivered in the "0" position by default "0".
6.2.1 Operating
"0" Both pumps are stopped.
"P1" Pump 1 runs permanently (pump 2 is not on standby).
"P2" Pump 2 runs permanently (pump 1 is not on standby.
"P1/P2" The pumps run alternately depending on the logical
status of the external clock control, with switching
on fault.
"P1 + P2" Both pumps run in parallel with a possible cyclical
stop of one of them depending on the logical status
of the external clock control, with switching on fault
(e.g. night operation).
"RESET" Manual reset of the system on "ipsothermic fault.
Comment : Each change in the operating mode causes a momen-
tary stop of the pumps (a few seconds).
6.2.2 Principle
The status of the open/closed contact sent by the clock enables the
running time of the pumps to be controlled according to the selec-
ted mode.
NB : The second pump comes on systematically on of the in service
pump.
P1/P2 mode
closed contact operation of P1 only.
open contact operation of P2 only.
NB : If one of the pumps stops, the start-up of the other is timed (a few
seconds).
"P1/P2" "¨P1 + P2"
P1 + P2 mode
Closed contact
Open contact
6.3 Switching clock (See FIG. 2 - ref. 8)
The selector (See FIG. 3 - ref. 1) must be in P1/P2 or P1+P2 position.
6.3.1 Setting the switching times
Selectors (See FIG. 4 - ref. 2)
Sélecteur (Voir FIG. 4 - rep. 2)
The selector must be on :
For the chosen switching times, move the blue segments to the left
(1 segment = 1 h 45) e.g.: Monday 12-24 hours.
6.3.2 Setting the day and the time (on energizing the box)
Turn the disc (See FIG. 4 - ref. 1) ) in the direction of the arrow to the
day of the week (1 to 7) and the time opposite the ref. " ".
e.g.: 1 = Tuesday and 6 = 6 am.
6.4 Remote control (terminal strip 7 FIG. 2)
This possibility enables the pumps to be stopped from a distance
without changing the operating mode and the cycle programmed
by the clock.
6.5 Fault offset (terminal strip 7 FIG. 2)
Main offset which changes the status on detecting a thermic or ipso-
thermal fault on one of the pumps.
There may be multiple applications: alarm, indicator light, emergen-
cy flashing, etc.
6.6 "RESET" function
The red LED (See FIG. 3 - ref. 2) showing the "RESET" mode :
- Lights up permanently on a thermal fault.
The light goes off on resetting the thermal relay or circuit-breaker lin-
ked to the pump.
- Blinks for a ipsothermal fault.
To turn off the light and enable restarting :
Re-starting is only possible if the temperature in the motor has
decreased to normal.
"Reset"
- Move the selector momentarily to "RESET" (anticlockwise rotation of
the selector (See FIG. 3 - ref. 1) in extreme position)
CAUTION
6.7 Pump reports (See FIG. 2 - ref. 7)
This option enables remote control of information on the pumps' sta-
tus (on/fault).
NB : the offset fault display is general, it does not distinguish a thermal
fault from an ipsothermal fault or pump 1 from pump 2.
7. MAINTENANCE
The box does not require any specific maintenance.

Move the selector back to the required operating
mode.
