IV.  Option C-2 Operation

A. 

Front Panel Display

a.  System Menu Functions:

Calibrate -  Conductivity of dissolved liquids.

Switch At -  Conductivity value in which the system will advance to the next bowl.

Spraying on #1 -  Identifies the bowl in use.  

Zero Cond -  Identifies the zero conductivity value.

b.  Run Mode Explanation:

Power- Illuminates when the controller is supplied with 120/240VAC.

Relay - Illuminates when a relay is activated. 

Alarm - Illuminates when the final bowl has been utilized.

c. 

Control Panel Buttons:

View- displays menu options screen and returns back to run mode.

Function Select- advances menu options. 

    Value 

Adjust- 

changes 

menu 

settings.

Test- activates relays and alarms on for 3 minutes.

B. 

Controller Set-up

  1.  Press VIEW then adjust the FUNCTION SELECT knob to view functions.

  2.  Stop on the desired function and use the VALUE ADJUST knob to change the value.

  3.  After setting a value, adjust FUNCTION SELECT knob again to advance to the next function.

  4.  Press VIEW after setting the controller to continue with the run mode.

  Note:  Press the TEST button to force all relays on, press again to force off, press again to return to  

normal operation.  If forced on or off, the unit will return to normal after 3 minutes.

System Operation

In order to activate the conductivity on the controller both level wands must be down (closed) to start, 

with the 1st relay on for spraying on bowl 1.  Both level wands must be up (open) to stop, to turn the 

“FILL” relays off. 

1. Upon startup, the conductivity of the solution in the tank has no effect on the controller.  The tank 

must be filled and emptied one time before the controller will consider the conductivity.  This simply 

means, the level wands must both go up to start filling the tank and then they must both go down to 

show an empty tank.  At this point the controller will accept the conductivity reading. 

2. When the conductivity drops below the “Switch At” point, the system will switch from Bowl #1 (Relay 

#1) to Bowl #2 (Relay #2), Bowl # 1 will have utilized the solid chemical by this point.  The first time 

the controller switches to Bowl #2, it will not consider the conductivity; once again, until the tank has 

been filled and emptied one time. 

3. The controller will continue operating on Bowl #2, even if the conductivity drops below the “Switch 

At” point while utilizing Bowl #2 the ALARM led will activate.  If the controller has option “H”, then a 

relay will also activate for the alarm.  This relay can be 120/240VAC or a dry contact.
