9.5.13. TANK DRAINAGE
With the encoder in the drainage position, when the START button is pressed on a front opening appliance (DIP1=0)
or the lid is closed on a top-loading machine (DIP1=1), the drainage cycle starts, and the machine active LED (L2)
flashes throughout the process.
During the drainage cycle, the drainage pump (BD) runs cycles of 17”ON/3”OFF for 120 seconds.
9.5.14. REGENERATION
If the regeneration is active (DIP2=1), with the encoder set to regeneration, irrespective of the door status, when the
START button is pressed, the regeneration cycle is run, and the machine active led L2 flashes for the duration of the
cycle which is equal to 20 minutes.
As can be seen from the diagram below, the RG output is active throughout the cycle, whereas the V output is
activated for the first 20 seconds and the Vreg output for the last 40 seconds.
If the V or Vreg outputs are active, the BD output is activated in parallel.
9.5.15. DIAGNOSTICS
Any faults arising in the machine are notified with impulse trains from the “L1” led. The trains are formed of X 0.5
second impulses ON and 2 seconds OFF , as shown in the diagram below.
Example of a 2 impulse train
The diagnostics defined are listed below:
1 Door open: If DIP1=0 (not top-loading) and START is pressed while IP=0 (door open): This is indicated by a
one-impulse train
2 Filling error: If PT=1 (tank not full) and Vreg=1 for 10 minutes: This is indicated by a two-impulse train
