5.7 Valve #1 & #2 Temperature Setting
1. Select Head 1(2) as the device you wish to set. This is accomplished by either pressing the “Loop Select Up” or
the “Loop Select Down” buttons until the green LED to the left of the “HEAD 1(2)” label is illuminated.
2. Use either the “Set Temp Increment” or “Set Temp Decrement” buttons to increment/decrement the desired
temperature.
5.8 Pump Function Mode Selector
These three LED’s indicate pump Cycle, Crawl, or Run, and are controlled by the Pump Function Toggle button.
• Cycle: The pump is cycled on/off when the pump-switch on a handheld or foot switch is activated. The same
condition happens when an automatic pattern control device is used.
• Crawl: The pump is normally on, turning at a slow fixed velocity. The crawl function keeps a constant pressure
from the pump, through the hose, and to the handheld or automatic mounted applicator. This ensures that when
the handheld/footswitch/automatic device is activated, the adhesive will be dispensed on demand with be no lag
time.
Note: Pump speed is not adjustable when in crawl mode.
• Run: The pump is always on.
5.9 Pump Speed Setting
When selecting cycle, crawl, or run, and the pump is activated for the purpose of dispensing adhesive; the speed of
the pump will be whatever is displayed on the pump speed indicator’s row of ten green contiguous LED’s. The
speed of the pump is adjusted by using the “Pump Speed Increment” or “Pump Speed Decrement” buttons. There is
also an “On/Off” switch, which is above the pump status indicator.
In all three of the above cases when the pump is activated for the purpose of dispensing adhesive, the speed of the
pump will be whatever is displayed on the pump speed indicator’s row of ten green contiguous LED’s. The speed of
the pump is adjusted by using the “Pump Speed Increment” and “Pump Speed Decrement” buttons. There is also an
“On/Off” switch, which is above the pump status indicator.
5.10 Heating Indicators
The series of Loop Output indicators refer to the tank, hose, and valve. The LED’s will flash amber while warming
up. Once the desired temperature has been reached, each LED Loop Indicator output will turn to a green color.
Note that all three LED’s should be a flashing green color before dispensing adhesive.
5.11 Melt Unit Ready Lights
When the Melt Unit is ready to operate, all three LED indicators as observed on the Loop Output Indicator row of
LED’s will flash green. Note that the pump will not operate until the Tank is at temperature. The tank is at
temperature when the associated LED is flashing green. The pump WILL operate even if the HOSE or Valve is
NOT at temperature.
Dispense the adhesive only after all of the LED’s have changed from a flashing amber color to a flashing
green color.
5.12 Open Sensor Error LED
This LED will be illuminated red in color when an open circuit condition is sensed. It could happen due to a faulty
applicator, a melt unit malfunction, or a hose that has failed. The affected zone is automatically de-energized which
provides a very accurate, simple, and fast turn-around time when there is a system problem. For example, if the
failure occurred in the Valve area, a new applicator could quickly and easily be replaced.
