REPAIR AND SERVICE 

The sensor should be cleaned and the operation should also be tested 
when  emptying  the  oil  storage  chamber  or  at  least  once  every  six 
months. The easiest way to check the operation is to lift the sensor up 
in the air and to put it back to the separator. The operation is described 
in chapter 3. 

For cleaning, a mild detergent (e.g. washing-up liquid) and a scrubbing 
brush can be used. 

In case of queries, please contact Labkotec 

Oy’s service. 

SAFETY INSTRUCTIONS 

OMS-1  control  unit  must  not  be  installed  in  potentially  explosive 
atmosphere. Sensors connected to it may be installed in zone 0, 1 or 2 
potentially explosive atmospheres. 

In  case  of  installations  in  explosive  atmospheres  the  national 
requirements  and  relevant  standards  as 

IEC/EN  60079-25  and/or 

IEC/EN 60079-14

 must be taken into account. 

Warning!  If  the  cabling  is  voltage-tested,  the  sensor  must  be 
disconnected. 

If  electrostatic  discharges  can  cause  hazards  in  the  operating 
environment,  the  device  must  be  connected  into  equipotential  ground 
according  to  requirements  with  regards  to  explosive  atmospheres. 
Equipotential grounding is made by connecting all conductive parts into 
same potential e.g. at the cable junction box. Equipotential ground must 
be earthed. 

The device does not include a mains switch. A two pole mains switch 
(250 VAC 1 A), which isolates both lines (L1, N) must be installed in the 
main power supply lines in the vicinity of the unit. This switch facilitates 
maintenance and service operations and it has to be marked to identify 
the unit. Fuse maximum 10 A. 

When executing service, inspection and repair in explosive atmosphere, 
the rules in standards 

IEC/EN  60079-17 and IEC/EN  60079-19

 about 

instructions of Ex-devices must be obeyed.
