11.4.6 Setting the confirmability of limit value 2
If limit value 2 is exceeded by one of the two
sensors, a sprinkling installation is usually triggered,
for example to bond the leaking chlorine.
Normally the relay for limit value 2 remains activated
until the measured value drops down below limit
value 2. However, it may be necessary to switch off
the sprinkling installation for example to implement
countermeasures. In this case, limit value 2 can be
set to allow confirmation.
"Confirm" means that the relay for limit value 2 is
deactivated (and therefore also the connected
sprinkling installation) even though the risk caused
by the increased gas concentration remains.
Warning
Mortal danger!
Use this function only if you are certain
that no large gas breakout has occurred!
Limit 2
to receipt OFF
1. Select whether limit value 2 should be confirmable
or not by pressing the [Up] or [Down] button.
2. Confirm by pressing [OK].
