Example
: the maximum cleaning time is set to 20 seconds. If the level switch will not return to its normal position after these 20 seconds a
safety procedure will be initiated. This procedure follows these steps:
1. The controller stops the motor and the cleaning pump/solenoid valve
2. The controller directs the motor to rotate in the opposite direction for 5 seconds and will clean with water.
3. The controller stops the motor and the cleaning pump/solenoid valve
4. The controller directs the motor in the normal direction and cleans with water according the set maximum cleaning time
5. The controller stops the motor and the cleaning pump/solenoid valve
6. The controller directs the motor to rotate in the opposite direction for 5 seconds and will clean with water.
7. The controller stops the motor and the cleaning pump/solenoid valve
8. The controller directs the motor in the normal direction and cleans with water according the set maximum cleaning time
If the level switch does not reach its normal position after these extra cleanings the ERROR led on the controller unit will start flashing red (2 x
per second) to indicate this anomaly. However, as soon as the level switch reaches its normal position (e.g. due to a slow filling system), the
ERROR led will go off and will be a continuous green led to indicate a normal situation.
AUTOMATIC CLEANING
The software of the controller offers an automatic periodic cleaning function that will perform a cleaning process of 10 seconds once per hour.
This cleaning process will take place independent of the level switch position. The automatic cleaning will not take place during a motor
ERROR.
MOTOR PROTECTION
Another advantage of our software based controller is the motor protection. Besides the already mentioned “slow start” feature, the controller
also offers a motor blockage protection. In case the motor is blocked, for whatever reason, it will try to move anyhow. This will cause a higher
amp use then in a normal (unblocked) situation. As soon as a certain threshold is exceeded, the controller will rotate the drum in the opposite
direction as an attempt to get rid of possible object that could block the drum. If this offers no solution and the threshold value is still exceed-
ed, the controller will stop the motor and the cleaning pump and the ERROR led on the controller will start blinking red (1 x per second). This
ERROR message will not disappear by itself, the user has to find out what causes the blockage and remove it. During this ERROR message the
controller will not clean the drumfilter. The ERROR message will only disappear after restarting the controller.
COVER SWITCH
Underneath the cover of the drumfilter is a small magnet that is in contact with a switch on the inside of the drumfilter housing. When the
cover is opened this contact is interrupted which will deactivate the motor, cleaning pump/solenoid valve and UV-C device. It prevents any
chance to personal injuries caused by strangulated body parts between moving parts and the possibility of persons looking into the UV-C
radiation.
WARNING!
Pressing the
TEST
button while the cover is removed will still activate the motor, cleaning pump/solenoid valve
and (optional) UV-C device! Only press this button if you are sure that no one could be harmed by this action.
Pressing the
TEST
button is at your own risk!
MAINTENANCE
It is recommended to regularly check all vital parts of the drum filter such as the motor, drum, spray nozzles, cleaning pump/solenoid valve,
etc. Pay special attention to the waste gutter for any obstructed waste particles such as leaves and blanket weed. These waste particles are
rinsed off with water but sometimes stay behind in the waste gutter. Remove these parts manually.
Dependant on the water hardness it can be necessary to remove calcium deposits on the filter screen elements. Calcium deposits can reduce
the flow of the filter screen elements. Use a mild anti scaling product such as cleaning vinegar.
