Remote start/stop, remote reset of faults/alarms
The power module of the controller is equipped with two digital inputs (DI6 and
DI8, M10 connector) for the remote control of:
- dryer RUN / STOP
- RESET Warnings/Alarms
NOTE
Preliminary operations A-, B-, C-, D-, E- must only be performed by
qualified and trained personnel.
A-
Remove power from the dryer and ensure that it cannot be restarted
accidentally.
B
Open the control panel door with the special key provided with the dryer
C
- Wire a potential-free contact [1] between the "DI6" and "GND" terminals of
the M10 connector ("REMOTE ON-OFF" command).
D- Wire a potential-free contact [1] between the "DI8" and "GND" terminals of
the M10 connector ("REMOTE RESET" command).
E-
Restore power to the dryer and switch it on at the main switch.
1-
With the stopped dryer press
to access the dryer's menu.
2-
Press
to display the list of process parameters and respective current
settings (“USER” profile).
3-
Touch the "DrC" parameter on the screen and set it to "REMOTE". Confirm
the setting with
, or
to exit the command.
4-
Press
to return to the previous screens.
5-
Close the "REMOTE ON-OFF" contact. The dryer will start up and the status
bar will turn green and display REMOTE ON.
6-
Open the "REMOTE ON-OFF" contact. The dryer will stop and the status
bar will turn blue and display REMOTE STANDBY.
NOTE
In "REMOTE" operating mode:
- It is impossible to operate and stop the dryer with commands from the display.
- It is impossible to manage and reset Alarms from the display.
- It is possible to carry out all other operations, such as the condensation drain
test, the management of Alarms and access to the function menu.
- Warnings/Alarms can be reset remotely via the "REMOTE RESET" contact
(see section "Changing process parameters", table "Advanced parameters").
[1] Use only a clean contact free from electric potential and suitable for
low voltage. Ensure there is adequate insulation on potentially
hazardous live parts.
10.15.13
“Alarm” and "dryer running" signal contacts
The power module of the electronic controller is equipped with two potential-free contacts for signalling about:
- dryer Warning / Alarm (RL3 contact, M3 connector)
- dryer in STANDBY / ON (RL4 contact, M4 connector). STANDBY=contact open, On=contact closed
The operating logic of the RL3 Alarm contact depends on the setting of the ACM parameter (see specific paragraph).
10.15.14
4-20mA analogue output
The power module of the electronic controller is equipped with one analogue output for external indication of the dew
point temperature (AO3 output, M9 connector):
The programming of the analogue output depends on the DPMin and DPMax parameters setting (refer to the specific
paragraph).
