Helpful Tips on the Titan Warewash System
Inductive Probe (82.28.1):
The inductive probe is particularly useful for situations where the C-12VIK probe is
experiencing considerable scale build up. The inductive probe is not affected by the scale build-up that the C-12VIK
would experience in a typical wash tank and does not need regular cleaning. There is also a temperature adjustment
feature on the probe that can be set to change the amount of soap for the temperature of the water. See instruction
sheet I-889 for more information.
Magnetic Field Sensors (82.23.1):
If trigger connection points cannot be established, the magnetic field sensors
(82.23.1) may be used in place of the trigger board and trigger wires. The magnetic field sensors connect directly to
the control board as shown on the wiring diagram. The magnetic field sensors can be placed on wash motors or rinse
valves to measure a magnetic field when the motors or valves are activated which will trigger the proper pump or
valve on the dispenser. See instruction sheet I-888 for more information.
Product Alarm Sensors:
The product alarm sensors are non-contact sensors to detect out of product conditions on
the detergent, rinse, and/or sanitizer. These sensors are plugged into the appropriate connectors at the bottom of the
control board. No programming or calibration is required. The detergent alarm sensor functions in addition to any
other alarm conditions.
Auto Switchover:
This feature allows for the automatic switching from Concentration to Probeless in the case of a
probe fault or inconsistent concentration readings. Conditions that can activate this feature are: (1) An Open Probe;
(2) A Closed Probe; or (3) Detergent not feeding properly, too much or too little detergent. The Titan will
automatically switch back to concentration once it detects proper probe conditions.
An OPEN probe is when a probe wire is disconnected or there is lime buildup on the tips of the probe. This will
cause an Auto Switchover. A CLOSED probe is when something for example, a piece of flatware, may be lying
across the probe tips. The Titan will wait 30 seconds to see if the short will clear. This will cause an Auto
Switchover.
If the Titan is reading an increase in detergent strength and does not reach set point in twice the time of the initial
charge setting for probeless mode, then the Titan will Auto Switch to probeless mode. (
Note: Factory default for
this initial charge is 15 seconds. This may not be enough time for the wash tank to reach its concentration
level. Watch the wash tank reach its level and determine the time it takes, then use this as the setting for the
initial charge in probeless to help from using the Auto Switchover feature when not necessary
). This is an
OVER feed condition. This is usually caused by a partially scaled probe, a leaking drain, a leaking water supply
valve, or excessive splashing of rinse water into the wash tank. This over feed condition is usually caused by
excessive wash tank dilution.
If the Titan is reading an excessive amount of detergent in the wash tank and the input is not lowering to the set
point in either 8 times the dwell time for conveyor mode or four times the dead cycles in door mode, then the Titan
will Auto Switch to probeless mode. (
Note: The factory default for dwell time is 90 seconds and for dead cycles
is 1)
. This is an UNDER feed condition. This is usually caused by no make-up water being added or extreme wash
tank contamination (very high soil load or washing salt shakers).
Feed Rate: Another possible cause of unnecessary Auto-Switchover is that the feed rate is not properly adjusted for
the tank size or feeding location. The purpose of the feed rate in concentration mode is to initially charge the tank to
obtain the set point without excessive over shoot. Factory Titans are set for a feed rate of 5 which is about a 4
second feed and a ½ second pause all the way to the set point. If the feed rate is too high, it will over charge the
wash tank and if the input does not return to the set point in 4 times the dwell time or dead cycles, the Titan switches
to probeless mode. To minimize this, set the feed rate as low as possible to achieve the initial charge as close to the
set point as possible. Water temp, pressure, discharge tube length, and probe placement can affect this feed time as
well.
Alarm Delay –
There are several detergents that are used by chemical companies that do not mix well with water
and will drop out of solution and settle at the bottom of the tank. When the machine is cycled again, the Titan will
read the higher concentration solution and turn the alarm delay off. It will then see no increase in concentration,
since the INPUT reading is below the set point. This is not a defect in the unit. It is due to the detergent. The Alarm
Delay setting should be changed to a few seconds before the end of the cycle to insure it will alarm.
When in Auto Switchover, the alarm delay should be set for less than 2 times the initial charge time or
approximately 80% of two times the initial charge time.
