Description

Schematic

Adjusting screw

Range: 8 – 28 bar
Setting: Turn the adjusting screw clockwise
for increasing the setting, and
counterclockwise for decreasing the setting
Factory setting: 19 bar

Bellows

Used for operating

Range setting
pointer

Indicates the setting

Only use the adjusting screw to change

the setting

Change over switch

Mode change at low speed, two settings
possible:

CutOff: fan motor will be stopped when
speed decreases to minimum speed
(45V% of R.M.S)

Min. speed: fan motor will be kept
running at minimum speed when speed
decreases to minimum speed (45V% of
R.M.S.)

Factory settings: CutOff

In order to protect the fan motor the

minimum speed is limited at 45% of R.M.S.
(V%)

Terminal board

Used for wiring, power supply is connectd to
terminals 1 and 2; terminals 3 and 4 to fan
motor. (See electrical diagram in one off the
panels)

¼” flare with
depressing pin

Used to connect the fan speed controller to the
liquid receiver.

Caution

For safety reasons,

NEVER

exceed the maximum pressure of the cooling unit. Set the high pressure

switch below the maximum allowed pressure, indicated on the identification label of the compressor.

For your information

1 bar = 100 kPa = 14.2 psi
