MELTER OPERATION
4-13
MA-5079-ENG MICRON GEAR ADHESIVE MELTER
Timer to switch between ON - Standby - OFF modes
This function is used to program automatic switching from the ON mode to
Standby mode after an inactive period of time (S-1) and from STANDBY mode
to OFF mode after another waiting period (S-2) during which activity has not
been resumed.
To program this function and ensure that it works properly, the melter must be
connected to the main unit via the CN4 external standby connector on the con-
trol board. The main unit will use this connection to send continuous signals
(not less than 500 ms) indicating that production is in progress. After the first
programmed time elapses without any activity (S-1) the equipment will switch
to STANDBY mode. If the equipment remains in standby and the ‘Standby’
push button is not pressed during the second programmed time (S-2), the
equipment will switch to OFF mode.
To set the equipment to the ON mode again, press the ‘ON/OFF’ push button
on the control board. The programmed S-1 time will begin a countdown the
moment the melter reaches the service temperature.
