CONNECTING
The relay switch off delay de-
pends on output’s power connected
to a three-phase power supply. The
lack of two phases causes immedia-
te sensor’s operation.
MOUNTING, FUNCTIONING
1. Disconnect the power supply from the mains
by the phase fuse, the circuit-breaker or the
switch-disconnector that are joined to the pro-
per circuit,
2.
Check if there is no voltage on connection
cables by means of a special measure equi-
pment,
3. Fasten the CKH-01 to the base with the screw,
4. Connect the cables CKH-01 with the hermetic
installation junction box according to installing
diagram,
5. Switch on power supply from the mains.
After power supply has been applied (from L1
phase) the sensor controls the correct phase order.
In case there is a wrong phase sequence, the relay
is switched off and the motor is disconnected from
power supply. The relay is switched on in case of
correct phase sequence, and the sensor controls
voltage values in particular phase. The relay re-
mains in on position and the controlled load (e.g.
motor) is switched on till the voltage value is cor-
rect 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 (185 V) the relay is
switched off (load switch off).There is a short time
delay in switching off the relay (t
2
from 3 to 5 sec).
The device is resistant to momentary voltage drops.
Another device switch on follows when the voltage
on a particular phase is above 190 V and exceeds
t
1
time (about 3 sec). Voltage hysteresis (about
5 V) switch off delay make the system resistant to
momentary voltage drops.
EXAMPLE OF INSTALLATION
The phase sequence sensor protects the motor does not
work in case of supply failure. The sensor enables the mo-
tor to work only when there is a correct phase sequences
CKH-01 phase sequence sensor belongs
to CKX asymmetry sensor family.
