basic maintenance procedures.

POINTS OF CAUTION

■ POWER INPUT RATING & OPERATIONAL RANGE

• Locate the power input rating marked on the product and
confirm its operational range as indicated below:

100 – 240V AC rating: 85 – 264V, 50/60 Hz, approx. 4 – 6VA
24V DC rating: 24V ±10%, approx. 3.5W
(for / T approx. 5 – 7VA)

■ GENERAL PRECAUTIONS

• Before you remove the unit or mount it, turn off the power
supply and input signal for safety.

• Be sure to put the terminal cover on while the power is
supplied.

■ ENVIRONMENT

• Indoor use.

• If the unit’s environmental protection IP65 is compro­mised (e.g. when multiple units are to be mounted side
by side) when heavy dust or metal particles are present
in the air, install them inside an enclosure with a proper
ventilation.

• Do not install the unit where it is subjected to continuous
vibration. Do not subject the unit to physical impact.

• Environmental temperature must be within -5 to +55°C
(23 to 131°F) with relative humidity within 30 to 90% RH
in order to ensure adequate life span and operation.

MODEL

ABF3

■ WIRING

• Do not install cables close to noise sources (high frequen­cy line, etc.).

• Do not bind these cables together with those in which
noises are present. Do not install them in the same duct.

■ AND ....

• The unit is designed to function as soon as power is sup­plied, however, a warm up for 20 minutes is required for
satisfying complete performance described in the data
sheet.

■ REQUIREMENTS TO ENSURE IP65

• Observe the designated panel cutout size (45 × 92 mm).

• Single mounting only. IP65 is not ensured when the units
are clustered side by side.

• The watertight packing included in the product package
must be placed behind the front cover.

• Both mounting brackets must be fastened tightly until
they hit the panel.

• Confirm visually that the packing is not contorted or ex­cessively run off the edge after installation.

■ HOW TO MOUNT THE UNIT ON A PANEL

1) Insert the unit into the panel cutout. The watertight
packing must be in place to hold the unit. Do not remove
it.

2) The IP65 protection is effective only with single mount­ing, with the designated cutout size (45 × 92 mm).

■ TERMINAL BLOCK

• How to remove the terminal cover

Insert the minus tip of a screwdriver into each hole at the
four corners of the cover and pull it to the direction as indi­cated below to separate the terminal cover.

Terminal Cover

• How to remove the terminal block
The terminal block is separable in two pieces. Loosen two
screws on top and bottom of the terminal block to separate.
Be sure to turn off the power supply, input signal and power
supply to the output relays before separating the terminal
block.

■ RETROACTIVE TIME PERIOD*

Digital Display Selector

The ABF3 continuously stores the MV output during CAS control. When the loop has been turned to MAN control (contact
closure at the terminals 9 – 10), it goes back by the preset time period and holds the output. For example, with the value set
to 10 seconds, the ABF3 outputs the MV value 10 seconds before the contact has been closed.
Selectable from 0 to 30 seconds in 1 sec. increments. (Factory set to 0 sec.)

1) Press IND button until the green LED turns on the CAS LED.

2) Press ▲▼ buttons until the digital display shows a desired value.

■ TRANSITION RAMP RATE

If the CAS control value at the moment of switching from MAN to CAS mode is greatly deviated from the MV output value in
MAN control, the ABF3 adjusts the difference gradually in the preset ramp rate. Receiving MAN command during transition
ramp period, the ABF3 turns to MAN mode after transition ramp function is completed.
The ramp rate is set as time required for the output goes from 0% to 100%.
Selectable from 0 to 30 seconds in 1 sec. increments. (Factory set to 1 sec.)

1) Press IND button until the green LED turns on the MV LED.

*1. OUT Switch cannot be controlled when PV, CAS, MV or MODE LED shows green.
*2. Add 0.3 seconds for the total time required to go from 0% to 100%.

CHECKING

1) Terminal wiring: Check that all cables are correctly con­nected according to the connection diagram.

2) Power input voltage: Check voltage across the terminal
19 – 20 with a multimeter.

3) Input: Check that the input signal is within 0 – 100% of
the full-scale.

4) Output: Check that the load resistance meets the de­scribed specifications.
