Type FF-

Insulation test

The device is equipped with extensive EMC protection. If insulation tests are carried out the electronic filter devices will be dam-
aged. All necessary tests have been carried out for all concerned groups of components at the factory (test voltage 1 kV or 1.5 kV
respectively, depending on the device).

Moisture and broken-wire alarms are signaled via two independent dry contacts.

They are made fail-safe in the FF-HM and FF-19 types: The relays switch when power is turned on and no moisture is detected,
they fall off when power fails, moisture or a broken wire is detected. Relays are used in the opposite logic with the types FF-..-U
(switched in the alarm case).

The devices have three LEDs (FF-3-U-2: five LEDs) for POWER, BROKEN WIRE and MOISTURE.

Alarms are monostable; they switch back after the cause for the alarm is removed.

Using the FF-HM or FF-19 type a 

hold function

 can be chosen by setting/wiring a jumper. The alarm will stay until the internal or

externally connected reset button is pressed.

4.2.1 Controller type FF-19

Note the drawing 

47/075-06-4

.

This type can only be used with a 24 V DC power supply. 

NOTICE! The grounding to PE has always to be attached!

The detector FF-40 is connected to PIN 30 and 31, the shield to PIN 2.

Connect the cable to the FF-3-N. Root strands white and brown to PIN 30 and 31, and shielding to PIN 2.

For FF-3-N and FF-40 the jumper J2 is set to 2-3.

When using older models (FF-1) jumper J2 has to be set to 1-2. Otherwise the controller would signal a broken wire.

Alarm hold function:

To select this function, jumper J1 has to be set to 2-3. An external reset switch or contact can be connected to PIN 26 and 27 of the
bus connector.

NOTICE! When using a detector without broken wire-detection, the broken wire alarm is not used. The relay contact may then
be used to look for power supply failure.

When installing the FF-3-N or FF-40 detector, both relays are used. A power supply failure may be seen by combining both alarm
outputs with an AND function since in working condition EITHER moisture alarm OR broken wire alarm is given.

4.2.2 Controller type FF-HM

Note the drawing 

41/073-01-4

 and 

41/074-01-4

.

On the upper terminal are the connections for power supply and alarm relay outputs, on the lower terminal the moisture de-
tector and the external reset switch are connected.

The type FF-HM-230 is suitable for 230 V AC and 115 V AC. 

The jumpers are factory set to 230 V AC.

 To change it to 115 V AC discon-

nect the jumper between terminals 9-10 and set jumpers to terminals 8-9 and 10-11. The power supply is connected to terminals
12-13 (PE is 7).

The type FF-HM-24 is only suitable for 24 V DC. The power supply is connected to terminals 12-13. 

NOTICE! Even with this control-

ler, PE has always to be connected to terminal 7!

Connecting the moisture detector:

The detector FF-40 is connected to terminals 25-26, the shield to 24.

Connect the cable to the FF-3-N. Root strands white and brown to terminals 25-26, and shielding to terminal 24.

When using models FF-3-N and FF-40, terminals 22 and 23 stay open to ensure broken wire detection.

When using older models (FF-1), a jumper must be set between terminals 22 and 23.

Hold function:

To enable this function, a jumper has to be set between terminals 20 and 21. An external reset switch or contact may be connec-
ted to terminals 14 and 15. The shield of this wire is connected to terminal 16.
