For installation of the controller, connect the mains voltage to the terminals in accordance

with the regulations. If a different mains voltage was not expressly ordered and was not given

on the voltage label, mains voltage of 230V AC 50-60 Hz (terminals L230, N, PE) or 110V

AC 50-60 Hz (terminals L110, N, PE) is always to be connected.

In order to attain a proper plant operation, the filter controller should be turned on and off via

the terminals E1(10) and E2 (11) or select DTC Mode 3. Application of the down-time-

cleaning functions is a condition on all Dantherm Filtration guarantees. The set of con-

tacts is potentialfree and is activated most appropriately by an auxiliary relay in the fan con-

trol system:

• Connecting the contacts E1, E2 sets the controller in operation.

• Disconnecting the contacts E1, E2 in DTC mode 1 means that the down-time-cleaning

process starts and when finished the filter controller stops. In DTC mode 2 starts the

down-time-cleaning-process only if the Delta-P DTCmax limit is exceeded in the last op-

erating period.

• In DTC mode 3 starts the down-time-cleaning process when the Delta-P DTCmax limit is

exceeded in the last operating period and the pressure afterwards reached the Delta-P

DTCmin limit.

Where the dust removal system includes automatic components, these should also function

during down-time-cleaning periods. Signals for this purpose are available at the terminals S1

and S2. (Signal if compressed air cleaning is activated, no signal if e.g. Delta P is below DP-

MIN during operation).

The hose connections P1 and P2 are to be connected to the hose connections on the filter as

shown in fig. 8. The hose connection is for hoses with 4 mm internal and 6 mm external di-

ameter.

The pressure gauge cell is suitable only for measuring non-aggressive, dry gases and must be

shielded against pressures exceeding 12.000 Pa.

Cable installation

All unused cable plugs should be taken off and replaced with dummy plugs.

Care should be taken to tighten the screws on all cable plugs firmly, to place them directly

against the cable and to prevent any penetration of moisture.

Displaying and parameter setting

Selecting the parameter:

To change from the operating mode to the parameter selecting mode press the

buttons (Fig. 4, 2.1 and 2.3) for more than 3 seconds. Go through the parameters by pressing
