7.The valve position limit switch enables the right bed heater and provides an input signal to the programmable relay when actuated by the cam lobe. When the cam verifies position is high, the right bed is activated. When the cam verifies position is low, the left bed is activated. Each heater is ON-OFF controlled.

8.Upon completion of the HEAT portion of the regeneration sequence, the regen heaters are disabled by the programmable relay and the COOL time begins.

9.Once the Cool time has expired, the valve motor is turned on until the cam switch makes a transition. Upon making a transition, the timing sequence is restarted for the new bed.

10.When no fault conditions exist, the display reads “SYSTEM NORMAL”.

11.The top 2 lines of the display show the HEAT and COOL times (in minutes) for the regeneration sequence. Changes to these times can be made by the operator as follows:

a.Press the up or down arrow until the cursor is positioned at the number to be changed.

b.Press the “+” key to increment the number, or the “-“ key to decrement the number.
