Alarm signal of the pressurized enclosure system
The pressurized enclosure system activates an alarm signal when it is interrupted. The
alarm signal can be reported via a relay switching contact.
● Enclosure GMS815P-PS-2G : The alarm switching contact connections are in the con-
trol unit of the pressurized enclosure system ( → Pressurized Enclosure System Operat-
ing Instructions).
● Enclosure GMS815P-PS-3G: Switching contact relay “Operating current circuit 2” is
available in the control unit of the pressurized enclosure system.
▸
Configure the pressurized enclosure system so that the alarm signal activates this
switching contact (
→ Pressurized Enclosure System Operating Instructions).
▸
Connect the alarm signal lines to this switching contact.

Signal connections (I/O) in the interface box
– Only valid for versions with interface box –
3.7.1
Function of the interface box
Signal connections of the gas analyzers are not directly available on the I/O modules in the
enclosure but in the interface box (
→ p. 21, Fig. 2 ). Not all signal connections can be used
with the interface box but just 16 signal lines (standard terminal assignment → p. 21, Fig. 2 ).
Each signal line in the interface box runs via a relay switching contact. If the pressurized
enclosure system is not ready for operation or is interrupted, the relay switching contacts in
the interface box are open, i.e. the signal lines are interrupted.
3.7.2
Connecting signal cables in the interface box
▸
Connect all signal lines in the interface box.
– Terminal assignment
→ p. 21, Fig. 2
– Connection terminals → p. 21, Fig. 3

Function of signal connections → “I/O module” Supplementary Operating Instructions.
▸
For versions with intrinsically safe signal connections (option): Observe the informa-
tion on intrinsically safe signal connections ( → p. 24, §3.9 ).
● Signal connections for versions without interface box → p. 22, §3.8

Instructions.
