4.2 All-purpose relay outputs (PK1 – PK3)
Control Unit is fi+ed with three all-purpose relay outputs. The outputs can operate in one of the two
statuses: as enabled or disabled. The terminals are then connected as shown in the diagram below.

Program Descrip!on Addi!onal parameters
Bi-colour green
indicator Correct system opera on – con nuous light. A er exceeding
warning 1 and 2 threshold – modulated light. A er exceeding
alarm threshold and in case of fault – light off. Principle of
opera on see figure 6. -
Bi-colour
indicator red Correct system opera on – light off. A er exceeding warning
1 and 2 threshold – modulated light. A er exceeding alarm
threshold – con nuous light. In case of fault – light off.
Principle of opera on see figure 6. -

WARNING 1 The output enables when warning 1 threshold exceeding is
detected at any detector. It is disabled when gas
concentra on measured by all detectors is lower than
warning 1 threshold. Enable delay
2
.
Disable delay.
Normally open (NO) opera on logic/
normally closed (NC)
3
.
WARNING 2 The output enables when warning 2 threshold exceeding is
detected at any detector. It is disabled when gas
concentra on measured by all detectors is lower than
warning 2 threshold. Enable delay.
Disable delay.
Normally open (NO) opera on logic/
normally closed (NC).
Alarm The output enables when alarm threshold exceeding is
detected at any detector. It is disabled when gas
concentra on measured by all detectors is lower than the
alarm threshold. Enable delay.
Disable delay.
Normally open (NO) opera on logic/
normally closed (NC).
2 Parameter enable delay and disable delay can range from 0 s ÷ 5400 s (90 min)
3 Selec ng the “normally closed” op on causes status change between ac va on and deac va on (see figure 5)
