will begin to count again.

2. Open lid alarm
When you open the lid of the hot-melt melter grid, the magnetic sensor gives
the signal to the programmable relay to interrupt the loading procedure.
Closing the lid, after 10 sec. the loading procedure restarts.
If keep the lid open longer than the time programmed into the parameter
‘ALARM’, the alarm is triggered and connects the warning signs:
- Beep buzzer.
- Amber light blinking signal in the control panel.
Both signals remain activated while you do not act on them.
Pressing the black button the acoustic signal stopps.
Pressing the amber light reset button the system restarts except if the lid is
still open.
When either of these alarms occurs, the loading cycle stops if it had not yet
begun, or does not begin if the equipment is in standby. The electrovalve
output is deactivated, the warning light flashes quickly and the buzzer starts.
The screen shows ‘T.AL 00:00m’ and you can program the first digits in
minutes and the digits after the “:” in seconds.
Setting programmable times using the timer
Inside the electric cabinet there is a programmable relay to set the
disconnection delay time of the electrovalve (T.EV), the error alarm (T.AL) and
the standby (T.ST) for periods of inactivity.
To open the electric cabinet, loosen the screw that holds in place the door to
the electric cabinet casing on the left side, and slide it out.
The following is the procedure to change the times for each element:
1. Press the ESC key for several seconds until the cursor appears under
the first digit of T.EV.
2. Use the left-right arrows to move to the value you want to change.
Click OK and you will see the digit in negative (light digit over a dark
background).
3. Change the T.ST value with the up-down arrows.
4. Use the left-right keys to move to a different digit.
5. Once finished, click the OK key to validate the changes and exit editing
mode by pushing ESC. The change is now in operation.
