4.3.3 EXKOP
®MINI
Safety Controller – initialization
After switching on the operating voltage, the EXKOP
®MINI
Safety Controller conducts a
self test. All internal and external signals will be checked. If LED’s of the KFD2-ST2-
Ex2.LB-Electronic lights “green” and pressure inside the tank of QV II Quench Valve
is built up, the EXKOP
®MINI
Safety Controller will be armed by pressing the Reset
button.
Now the EXKOP
®MINI
Safety Controller is armed.
5.0 Function check
The EXKOP
®MINI
System has to be checked monthly by using the test button.
Before carrying out the system check the plant safety representative must
ensure that no danger will occur during this procedure.
The test function simulates an activation of the EXKOP
®MINI
Safety Controller.
Therefore press the reset key for 5 seconds. This will cause all Quench Valves
connected to the controller to be closed immediately. The tests have to be
documented in the operating diary. Also all connected systems like process plant
computers, fire alarms or other safety devices will be activated.
According to the quantity of the connected Quench Valves following messages will be
dedicated: „Failure air QV X“ by LED’s. Until the air supply will not feed the air tanks to
the minimum pressure this status will not be changed.
After filling up all pressure air tanks the EXKOP
®MINI
Safety Controller can be armed
by the RESET key again.
The system check must be documented in the log book.
