Oil Alarm and Fault LED indicators are immediately on. 

 

Buzzer is immediately on. 

 

Relays de-energize after 2 sec of continuous pressing. 

 

 

 

When the Test push button is released: 

 

 

 

LED indicators and buzzer go immediately off. 

 

Relays energize immediately. 

 

 

Alarm on 

When pressing the Test push button: 

 

 

 

Fault LED indicator is immediately on. 

 

Oil Alarm LED indicator remains on. 

 

Buzzer remains on. If it has been reset earlier, it will return to be on. 

 

If relay 1 was already reset, it will de-energize again after 2 sec. of 
continuous pressing. 

 

Test will not affect relay 2, because it is already in alarm status. 

 

 

 

When the Test push button is released: 

 

 

 

The device returns without delay to the preceding status.

Factory settings 

If  the  operation  of  OilSET-1000  is  not  as  described  in  the  previous 
chapter, check that the device settings are as in figure 7. Change the 
settings according to the following instructions if needed.  

The  following  tasks  must  only  be  executed  by  a  person  with  proper 
education and knowledge of Ex-i devices. 

We recommend, that when altering the settings the mains voltage is off 
or the device is initialized before the installation is executed. 
 

 

Figure 7. Factory settings 

The  settings  are  made  with  switches  (MODE  and  DELAY)  and 
potentiometer (SENSITIVITY) located in the upper printed circuit board, 
and  the  jumper  located  in  the  lower  board  (figure  7).  In  figure  7,  the 
switches are as set in the factory. 

 

Switch S2 is used to set the 

operational delay of the control unit

. When the switch is in low 

position, relays operate and buzzer is on after 5 seconds after the level has reached the trigger 
level, and if the level still remains on the same side of the trigger level. 

When the switch is in high position, the delay is 30 seconds. 

Delays  are  operational  in  both  directions  (energizing,  de-energizing).  Alarm  LED  follows  the 
sensor current value and trigger level without delay. Fault alarm takes place after a fixed delay 
of 5 sec.
