Dehumidifier ML420-MLT1400
5 Commissioning
The ML420-MLT1400 dehumidifiers have several standard functions that need to be set before initial
start-up. Some of the functions require connection to external equipment.
Some features require connection of external equipment. For wiring details, see the wiring diagram.
5.1 Settings before start-up
5.1.1 Continuous process air fan operation
Standard settings automatically activate the process air fan only when dehumidification is required.
However, continuous process air flow can be desirable even when dehumidification is not required.
Continuous process air flow can be set, see the wiring diagram.
5.1.2 Single-stage humidity sensor
NOTE!
When no humidity sensor is connected, the dehumidifier will run at maximum effect continuously.
If a single-stage humidity sensor is fitted, this will switch the dehumidifier on and off. A single-stage
humidity sensor is connected according to the wiring diagram.
To maintain air circulation, preselect continuous operation of the process air fan even though
dehumidification is not required. For further information, see section
5.1.1, Continuous process air fan operation .
5.1.3 Two-stage humidity sensor
NOTE!
When no humidity sensor is connected, the dehumidifier will run at maximum effect continuously.
If a two-stage humidity sensor is connected, this will control the reactivation heater in two stages. The
reactivation power is controlled on the basis of the humidity sensor reading and the setpoint. A two-stage
humidity sensor is connected according to the wiring diagram.
To maintain air circulation, preselect continuous operation of the process air fan even though
dehumidification is not required. For further information, see section
5.1.1, Continuous process air fan operation .
5.1.4 Remote fault indication
The PCB display can be used for a general indication of the following faults on the dehumidifier:
■
Process air fan
■
Reactivation air fan
■
Drive motor
■
Heater
■
Auxiliary equipment input
■
Rotor has stopped (if this option is installed)
■
Blocked process air filter (if this option is installed)
■
Blocked reactivation air filter (if this option is installed)
