EXAMPLE OF INSTALLATION
WARNING!
The relay system is powered from
L1 phase. The relay switch off time delay
depends on output power connected to a
three–phase installation. The lack of two
phases causes the sensor to switch on.

PRODUCT FAMILY
CKM-01 phase sequence sensor belongs to
CKX asymmetry sensor family.
1. Disconnect the power supply from the
mains by the phase fuse, the circuit-bre-
aker or the switch-disconnector that are
joined to the proper circuit,
2. Check if there is no voltage on connec-
tion cables by means of a special me-
asure equipment,
3. Install CKM-01 device in the switchbo-
ard on TH-35 DIN rail,
4. Connect the cables with the terminals
according to installing diagram,
5. Switch on the power supply from the
mains,
6. Adjust voltage threshold that switches
on phase sequence sensor.
After power supply has been applied
(from L1 phase) the sensor controls the cor-
rect phase order. In case there is a wrong
phase sequence, the LED red switches on
marked „
” (outputs 11–12 are closed, the
motor is switched off, the alarm is switched
on). The LED green switches on in case
of a correct phase sequence „ ” (outputs
11–14 are closed, the motor is switched on)
and the sensor controls voltage values in
particular phase. The relay remains in on po-
sition and the controlled load (e.g. motor) is
switched on till the voltage value is correct in
every phase. In case there is a lack of any of
the phases or there is a voltage drop below
the adjusted asymmetry threshold the relay
is switched off. There is a short time delay in
switching off the relay (t2 from 1 to 5 sec).
The device is resistant to momentary volta-
ge drops. Another motor switch on follows
(outputs 11–14 are closed) when the voltage
is 10V higher from the adjusted voltage thre-
shold (voltage hysteresis), and after t1 time
(from 5sec to 10sec) is over. LED diodes
are switched on till every phase voltage is
below 50 V.

The phase sequence sensor protects the motor does not work in case of supply
failure. The sensor enables the motor to work only when there is a correct phase
sequences.
