Electrical Connection - Pahlen Level control 11250 User Manual

Level control
– in skimmer WIDE
1. The slide angle bracket and the fixation bar that comes with the level
control is not used in this installation, but bracket kit 112504 is needed
(option).
Mount the floater switch in the metal angel bracket.
2. Mount the angle bracket on the cover with screw M6 and washer (comes
with the bracket kit).
3. Fasten the cover inside the skimmer housing on the two weld screws
with the two nuts (M5) that comes with the bracket kit.
4. Adjust the water level by loosen the screw a little and slide the angle
bracket in the bar to required level. Then fixate it by tighten the screw.
Solenoid valve (option)
Solenoid Valve 112501 may not work with back pressure from the pool side but must be connected depressurized and installed
according to the "broken water", ie tap water to the pool shall have backflow protection and air gap. Thats why filling usually is
mounted above water level inside the skimmer.
(Magnetventilen kan inte arbeta med mottryck från poolsidan.)
The flow direction (arrow direction) as indicated on the magnetic valve is strictly to be observed! The mark is to be found
near the threads IN and OUT on the brass housing. The valve closes tightly only in the specified direction of flow. In the opposite
direction, the solenoid valve may be damaged.
The piping system must be cleaned before the valve installation, becauce dirt will malfunction.
The solenoid may be inserted or removed from the control box only when the power is off.

Electrical connection

• The electrical connection may only be carried out by an accredited
electrical specialist!
• The following connecting diagram and the corresponding prevailing
safety regulations must be observed.
• The supplier of the electric device should provide an earth leakage
circuit breaker with I <= 30mA.
FN
• Note! Small voltage lines near three-phase (or alternating current)
cables is to be avoided due to risk of signal interference.
Level control and control box
• The sensor cable may be extended up to 50m by use of a shielded cable
(2x0.75mm²). The shielding is to be connected with clamp 4.
• Please note, that it is absolutely necessary to carry out the connections water-proof.
The connecting cable of the float switch must not be wired together with other live wires.
• On finishing the installation the power supply may be switched on and you can carry out a functional check. Near the lower
retaining ring the floater closes the float switch and opens it again approximately 5mm above.
• The green diode on the board inside the control unit flashes immediately when the water level (floater top) has reached,
however, the magnetic valve closes only some seconds later. This time delay works in the same way on opening and on
closing and prevents frequent switching processes caused by undulations of the water in the swimming pool.
• If the diode glows slightly with opened float switch, should cable extensions be checked for creeping current caused by
humidity. The magnetic valve is closed in case of interruptions (damage) of the sensor cable, whereas a short-circuit
(e.g. due to humidity) of the sensor cable causes an opening of the magnetic valve.
Failure indicator
A red light marked "Alarm" is placed in the front lid of the control unit. If this light flashes there is a failure and the magnetic
valve for the refilling of water is switched off. The cause of the defect may be found in the area of the level sensor.
A foreign body floating on the water could have blocked the floating body of the mini liquid level switch.
After having settled the cause of the defect, the failure indicator can be switched off by first switching off the level
control with the rocker switch in the front lid and another switching on after some seconds.
Time monitoring
The time monitoring (= overflow protection) will become active, if the magnetic valve has been
uninterruptedly opened for a longer period of time (safety time period). An adjustment regulator is
placed on the control board that is used to select the safety time period.
Set the desired maximum time limit (30 minutes – 4 hours) or the alternative no safety time period
= >time monitoring is switched off.
On exceeding this safety time period the magnetic valve will be switched off.
