The controller module on the DMC50 control unit is provided with a digital input
set up for dryer start up (ON) - stop (STANDBY) mode from a remote
workstation.
1- Only qualified and skilled personnel are authorized to run electrically-
operated devices. Prior to undertaking maintenance measures at the device,
the following requirements must be met:
Make sure that the power supply is switched off and that the device is off and
marked for maintenance measures. Please also ensure that the power supply
cannot be re-established during the works.
2-
Wire a clean contact, free from electric potential, to terminals 17 and 18 on
the DCM50 control unit's power module.
3-
Set the DrC parameter to REMOTE mode (see section 8.15.14)
4-
Close the contact. The dryer will start up and the status bar will turn green
and display REMOTE ON.
5-

when in REMOTE mode. However it is possible to carry out all other
operations, such as the condensation drain test, the management of
alarms/service warnings, and access functions menus.
Only a clean contact free from electric potential and suitable for low
voltage must be used. Ensure there is adequate insulation on
potentially hazardous live parts.

1-
Set the ACM (Alarm Contact Management) parameter to the required
mode (see section 8.15.14).
Dryer powered and absence of the conditions checked with
the ACM parameter settings
