5.13 Auxiliary Input Connection and Control Setting
One auxiliary connection is available for each hose/applicator employed. Different examples of an auxiliary device
might be: foot switches, a timer or controller, or an external kit, which would allow you to apply adhesive in
different patterns and pressures (such as a swirl pattern when using a swirl tip).
Auxiliary input selection is accomplished on a per channel basis and can only be accessed when the control is in a
Standby Mode. First press the Standby Toggle at the top center of the control panel. The system will go into
standby and allow the changes to the auxiliary mode. Next, using the Loop Selection up or down button, select the
channel to which you chose to activate or de-activate. When the channel is selected, just press the Loop Select
on/off button and make the desired selection. After the selection is completed, just press the Standby Toggle button
again and the change is complete.
5.14 Standby Timer Setting
Setting the standby timer will reduce the tank temperature for a selected amount of time. When the standby time is
complete, the tank settings automatically resume to previous set temperatures.
1. Press the Standby toggle.
2. Press temperature increment/decrement to increase or decrease time. Set time will appear in the set temperature
display. You must enter a minimum of five minutes for standby time.
5.15 “Drastic” Reduction of the Tank Temperature
“Drastic” reductions in temperature of the tank will cause the melt tank circuit breaker to trip. This is a safety feature
to protect the unit from damage. This condition can occur if the operator tries to adjust the “TANK” temperature
from Range-5 to a Range-2. If this function is invoked, the system thinks there is an over-temp condition. To
prevent this “thermal runaway” condition from doing damage, the breaker trips, and all power is cut off. This
situation may be easily remedied by allowing the tank temperature to cool down before resetting the circuit breaker.
5.16 “Drastic” Reduction of Hose or Valve Temperature
“Drastic” reductions in temperature of the hose or valve once they are at operating temperature may result in a
sensed over-temperature condition for that zone. An audible alarm will be sounded and the OVER TEMP LED on
the front panel will be illuminated and heating for that zone will be disrupted.
5.17 Cold Temperature Start-Ups
1. Attempting to start-up the melt system at ambient temperatures below 42° F (6° C) with the melt unit set at
Range-4 or higher may result in an “open circuit” condition being sensed by the melt unit. This condition will
prevent that “open” zone from heating.
2. This condition is remedied by adjusting the temperature range for the “open” zone to a lower setting. This
setting may be adjusted back up to the desired higher setting once the tank, hose, and head have warmed to a
temperature above 42° F.
