The CKH-01 phase sequence sen-
sor device is used to protect devices
powered from a three-phase installa-
tion (e.g. a motor) from being damage
in case of phase voltage switch off. It
is because of phase voltage asym-
metry or wrong phase sequence. The
threshold value switch on is preset to
185 V and it can not be regulated by the
user. The system does not protect from
voltage drop asymmetry and it is powered
from L1 phase. The switch off delay and
voltage hysteresis cause the system is re-
sistant to momentary voltage changes.

The device is designed
for three-phase installa-
tion and must be instal-
led in accordance with
standards valid in a par-
ticular country. The de-
vice should be connec-
ted according to the details included in
this operating manual. Installation, con-
nection and control should be carried out
by a qualified electrician staff, who act in
accordance with the service manual and
the device functions. Before installation
make sure the connection cables are
not under voltage. The cruciform head
screwdriver 3,5 mm should be used to
instal the device. Improper transport, sto-
rage, and use of the device influence its
wrong functioning. It is not advisable to
instal the device in the following cases: if
any device part is missing or the device
is damaged or deformed. In case of im-
proper functioning of the device contact
the producer.
