Standby Temperature Difference
In Standby mode, the temperatures of all active temperature zones decrease by a programmed
amount and the pump(s) stop pumping adhesive.
The programmed decrease in zone temperatures is the standby temperature difference. The
standby temperature difference applies to all zones once standby is activated. For example, if
the difference temperature is 80F, and setpoints are 300F, then all zones will reduce to 220F
(300 ‐ 80 = 220) when standby is activated.
After turning the Input Wheel to select Standby Configuration, press the Enter Knob to advance
to the screen. Press the Enter Knob to select the first parameter, ie. temperature difference.
Press the Enter Knob again to highlight the temperature difference value. Then turn the Input
Wheel to program your desired value. Confirm your choice by pressing the Enter Knob.
Standby Time Delay and Activation
The standby time delay is the programmed number of minutes until standby takes place after
activation by either an external contact (for example: a PLC or an external switch) or by a pump
stoppage. The default time delay is 0 minutes (immediately!). The programmable range of the
standby time delay is 0‐150 minutes.
Turn the Input Wheel to select the time delay parameter (ie. Standby X min. After…). Press the
Enter Knob. Turn the Input Wheel again to select your desired minutes value. Confirm your
choice by pressing the Enter Knob.
Now turn the Input Wheel to select the After Ext Contact/ After Pump Stop field. Press the Enter
Knob and then turn the Input Wheel to highlight your choice of activation. Confirm your choice
by pressing the Enter Knob.
Sleep Mode After Standby
Sleep mode shuts the ASU off after it has been in standby for a programmed length of time. This
length of time can be from one hour to 99 hours. Or you can choose to program the unit to have
no sleep mode by programming “ ‐ ”. When the unit is in sleep mode, the Main Screen displays
“System Off, Switch On with Enter Knob”.
Turn the Input Wheel to select the Sleep Mode After # Hrs In Standby field. Press the Enter Knob
to highlight the hours value. Turn the Input Wheel to select your desired hours value. Confirm
your choice by pressing the Enter Knob.
Press the RETURN button to return to the System Configuration Menu.
Level Detection (P2)
The level detection sensor triggers an alarm when the liquid adhesive level in the hopper falls
below a certain level. Hopper Empty is the alarm message displayed on the controller's status
line.
