1 Introduction
1.1 Intended use
A moisture detector is a device which signals moisture in the gas flow of a sample gas treatment system. Here the electrodes
separated by a gap are located inside the Gas flow.
The circuit devices Type FF analyse the moisture detector FF-3-N and FF-40. These devices allow the analysis of moisture ingress
in the sample gas detected by the moisture detector, and to trigger an alarm.
1.2 Types
These operating instructions apply to the following devices. Please refer to the nameplate to identify your model.
Moisture detector and mounting adapter
FF-3-N moisture detector with cable break detection
FF-40 moisture detector with cable break detection, max. pressure 40 bar
Type G flowcell in PVDF
Type S flowcell in stainless steel
Controllers Voltage Connectible moisture detectors
FF-HM-230 for rail mounting 230/115 V AC for one FF-3-N moisture detector or FF-40
FF-HM-24 for rail mounting 24 V DC for one FF-3-N moisture detector or FF-40
FF-19 19" rack 24 V DC for one FF-3-N moisture detector or FF-40
FF-1-U inside small casing 230/115 V AC for one or two moisture detectors FF-1
FF-3-U inside small casing 230/115 V AC for one FF-3-N moisture detector or FF-40
FF-3-U-2 inside small casing 230/115 V AC for two separate FF-3-N or FF-40
The functionality and operability is identical for all controllers. Differences in the pin assignment are indicated accordingly.
Please note: proper functionality can only be guaranteed when using the specified moisture detectors with the controllers.

2.2 General hazard warnings
The equipment must be installed by a professional familiar with the safety requirements and risks.
Be sure to observe the safety regulations and generally applicable rules of technology relevant for the installation site. Prevent
malfunctions and avoid personal injuries and property damage.
The operator of the system must ensure:
– Safety notices and operating instructions are available and observed,
– The respective national accident prevention regulations are observed,
– The permissible data and operational conditions are maintained,
– Safety guards are used and mandatory maintenance is performed,
– Legal regulations are observed during disposal.
Maintenance, Repair
Please note during maintenance and repairs:
– Repairs to the unit must be performed by Bühler authorised personnel.
– Only perform conversion-, maintenance or installation work described in these operating and installation instructions.
– Always use genuine spare parts.
Always observe the applicable safety and operating regulations in the respective country of use when performing any type of
maintenance.
DANGER Electrical voltage
Electrocution hazard.
a) Disconnect the device from power supply.
b) Make sure that the equipment cannot be reconnected to mains unintentionally.
c) The device must be opened by trained staff only.
d) Regard correct mains voltage.
DANGER Toxic, corrosive gases
The measuring gas led through the equipment can be hazardous when breathing or
touching it.
a) Check tightness of the measuring system before putting it into operation.
b) Take care that harmful gases are exhausted to a save place.
c) Before maintenance turn off the gas supply and make sure that it cannot be turned
on unintentionally.
d) Protect yourself during maintenance against toxic / corrosive gases. Use suitable pro-
tective equipment.
DANGER Potentially explosive atmosphere
Explosion hazard when used in explosive areas
The equipment is not suitable for use in explosive areas.
Never operate moisture detectors located in flammable or explosive gas mixtures on the
device.

3 Transport and storage
The device should be only transported in the original case or in appropriate packing.
If the device is not used for some time, protect it against heat and humidity. Store the device in a roofed, dry, and dust free
room. Temperature should be between –20 °C and 40 °C (-4 °F and 104 °F).

4 Installation and connection
4.1 Mounting
4.1.1 Mounting of moisture detector and adapter
The flow adapter is equipped with internal threading, G1/4 or NPT1/4 (flow adaptor marked with NPT), for the gas connections
and G1/4 for the moisture sensor. The drawing you find on the backside of the attached data sheet. As well the fittings as the
moisture detector must be used with Teflon sealing or an O-ring to assure proper sealing of the sample stream. Please assure
that the wires are guided tension free.
If there’s particulate or aerosols in the sample gas, a filter has to be installed upstream the detector. Otherwise the particulate or
aerosols can build a layer on the detectors surface inhibiting its function.
The wire should NOT be put into one cable channel with power switching cords. The function can be influenced otherwise.
It might be necessary to adjust the position of the humidity sensor in strongly fluctuating ambient or component temperatures
in order to ensure the necessary tightness in the system.
4.1.2 Mounting of detector-controller
Controller type FF-19
This type is designed as an insert for 19"-housings. The bus connector is a DIN 41612 type B. Used pins of columns a and c are
plated through.
Before inserting the FF-19 into the housing, set the jumpers.
Controller types FF-HM
The type FF-HM is designed for standard 35 mm rail mounting according to DIN EN 50022.
Controller types type FF-..-U
For mounting disassemble the cover by loosening the 4 black screws. The holes for the mounting screws are below the black
screws. Mounting dimensions are 165 mm x 79 mm (6.5" x 3.1"). They are made for screws M4, the screws head should be at least
6 mm (0.24") in diameter.
4.2 Electrical connections
WARNING Hazardous electrical voltage
The device must be installed by trained staff only.
CAUTION Wrong mains voltage
Wrong mains voltage may damage the device.
Regard the correct mains voltage as given on the type plate.
WARNING High voltage
Damage to the device in case of insulation testing
Do not proceed insulation tests with high voltage
to the device as a whole!
