ENGLISH
6.3.5.2 A mains water system monitoring pressure switch +
manometric contactor
- Set the water shortage protection switch (see FIG. 2 ref. 11).
In this position, the control manometric contactor is connected at
contactor terminals 5 and 6.
Setting the time-lag before re-start.
Following a stoppage due to lack of water, select the waiting time
before re-start (1 to 30 minutes).
This is set on the potentiometer (see FIG. 2 ref. 8).
8 . OPERATING TROUBLES
Before starting any service repar work, CUT OFF THE POWER
SUPPLY TO THE BOX.
INCIDENT
1) THE PUMP WON'T START
OR KEEPS STOPPING
2) PUMP FAULT ON
STARTING
3) PUMP FAULT
PERMANENT RED LIGHT
4) FAULTY AUTOMATION
5) THE PUMP WILL START
BUT THE FLOW RATE IS
NOT HIGH ENOUGH
CAUSE
a) The connection to the power supply is
incorrect :
b) The voltage selection fuse (see FIG. 2 ref. 10)
has been inserted incorrectly or burn out :
c) Operating mode in "0" position :
d) Opening of the remote control circuit :
e) No connection of sensors, floats
or shunts :
f) Circuit-breaker open :
a) Protection problem :
b) Incorrect wiring :
a) Triggering of thermal protection :
a) Bad ground connection :
b) Abnormally soft water :
c) Time-lag at zero :
a) Rotary speed too low :
b) The pump is turning in the wrong direction :
7. MAINTENANCE
The YN7000 box does not require any particular maintenance.
a) Reconnect the power supply according to the
voltage available.
b) Place the fuse in the correct holder. Change it
if required.
c) Move the selector (see FIG.1 ref.5) to the
"AUTO" position.
d) Close the circuit or check for the presence of
a shunt (contactor terminals 5 and 6).
e) Connect the sensors, the floats or insert the
shunt according to use (see FIG. 4).
f) Close the circuit-breaker.
a) Check the status of the relay.
b) Check the wiring.
a) Check that the setting threshorld conforms
with the identification plate on the motor (See
§ 6.2.1). Reset by pressing the "RESET" button.
If the fault pertsists, contact ASS.
a) Check the earth connections and the
grounding of the pump.
b) Check the setting (see § 6.3.1.1).
c) Check that the time-lag is functioning and is
set correctly.
a) Check the mains voltage and the motor
coupling.
b) Swap round the two phase wires at the box's
mains supply.
