FEATURES

DESCRIPTION

APPEARANCE

●  Wrong phase sequence protection,

●  phase fading protection,
●  voltage asymmetry protection,
●  (asymmetry) switch on threshold regu-

lation,

●  switch off delay and voltage hysteresis
●  resistant to momentary voltage drops,
●  momentary  voltage  fading  protection 

max 10 A capacity,

●  monomodular casing,
●  TH-35 DIN rail installation.

The CKM-01 phase sequence sensor 

device is used to  protect  devices powe-

red  from  a  three-phase  installation  (e.g. 

a motor) from being damage in case of 

phase voltage switch off. It is because of 

phase voltage asymmetry or wrong phase 

sequence. The threshold switch on value  

is  can be adjusted by the user by means 

of a potentiometer. The system does not 

protect from symmetrical voltage drop and 

it  is  powered  from  L1  phase. The  switch 

off delay and voltage hysteresis cause the 

system is resistant 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  devi-

ce  should  be  connected 

according  to  the  details  included  in  this 

operating manual. Installation, connec-

tion  and  control  should  be  carried  out 

by a qualified electrician staff, who act in 

accordance with the service manual and 

the  device  functions.  Disassembling  of 

the device is equal with a loss of guaran-

tee and can cause electric shock. Before  

installation make sure the connection ca-

bles are not under voltage. The cruciform 

head screwdriver 3,5 mm should be used 

to  instal  the  device.  Improper  transport, 

storage, 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.
