Function of Proportional Adapter
1.
General
The proportional adapter M 02719 (P- Adapter is a power device that
changes its operating time proportionally dependent on four different
controller inputs.
2.
Function
When the threshold value of 1.2 VDC (or 1.2 mADC) is exceeded, the relay
at terminal 13, 14 (refer to wiring plan, propartional adapter M02719)
switches the water intake valve to ON, provided that the supply voltage of
12 VAC is fed to terminals 11 and 12. If bath response (water tank level) of
48 VAC/50 Hz is given to terminal 9 and 10 of the proportional adapter, the
green LED illuminates. At the same time, the solid-state relay starts
operating with an operating time of 10%. This is indicated by flashing of the
red LED.
With the DIP switches installed on the printed board of the proportional
adpter, the operating cycles may be adjusted between 1 sec. and 3 sec.

An increasing value at the inlet of the proportional adapter causes an
extension of the operating time of the outlet. All inlets are uncoupled.
When the determined maximum value is achieved at one of the inlets, the
operating time of 100% has been reached.
