Probe Operation - Idex Knight Ultra Micro-Pro UMP 100 Series Instruction Manual

PROBE OPERATION

• With the detergent power "on", the conductivity probe
senses detergent concentration. When concentration
drops below the setpoint, the control automatically
turns on detergent feed.
Low and high concentration ranges allow easy setting
•
on all types of water conditions.
When the detergent concentration is within 15% of the
•
setpoint, the control automatically pulse feeds (3
seconds on / 2 seconds off) to prevent over-use of
chemical.
An "out of product" alarm will automatically sound if
•
the detergent setpoint is not reached in a specific time
period.
CONCENTRATION SETPOINT ADJUSTMENT
(1) With low range selected, slowly adjust the
detergent concentration pot clockwise a few
degrees. Detergent will pulse feed, then stop.
(2) Using a chemical titration kit, test detergent
concentration of the wash water. Continue to
increase the pot until the desired setpoint.
(3) If at full clockwise position of concentration pot and
wash water concentration is not strong enough, turn
pot back full counter-clockwise. Switch to high
range.
(4) Slowly adjust pot clockwise until detergent feed
begins, then stops. Using chemical titration kit,
continue adjusting pot until desired concentration
setpoint is reached.
ALARM DELAY SETTING
If the detergent setpoint is not achieved within the time
set on the alarm delay pot, the alarm will sound and the
unit will continue to feed. If the detergent setpoint is still
not reached within a second time frame (double the first)
the alarm will stay on, and detergent feed will stop.
(1) Delay time settings are:
Door 1 to 64 seconds
Conveyor 1 to 128 seconds
(2) For conveyor type dishwashers, adjust the alarm
delay to be slightly longer than the time it takes for
the unit to achieve the setpoint with a fresh tank of
water. For door type dishwashers, the alarm setting
should be calibrated to 5 - 10 seconds less than the
washcycle timing.
(3) Select low or high volume for the alarm.
