nitrogen gas generator
2.9 remote alarms and dryer control
Every nitrogen generator comes with three remote alarms as standard. In order to use the remote alarms, you are required to
install an additional four wired connections. First, you must install a wired connection into terminal ‘COM3’ (see item No.1
for reference) this will be the voltage that is then relayed back to your equipment. The relay outputs are capable of switching
any voltage from 5V to 277V AC / 125V DC and a maximum current of 7Amps. Next you will need to add an additional three
connections on each relay, terminal Q12, Q13 & Q14. (see item No.2, 3, 4 and 5 for reference). Each relay output relates to
a different alarm code;
•
(1)
Terminal COM3 - 5...277V AC / 125V DC, 50/60Hz, Max 7A
•
(2)
Terminal Q12 - Alarm output 1: Low inlet pressure alarm
•
(3)
Terminal Q13 - Alarm output 2: Low outlet pressure alarm
•
(4)
Terminal Q14 - Alarm output 3: High oxygen purity alarm
•
(5)
Terminal Q15 - Alarm output 4: Dryer Contact
When making wired connections to and from the generator, there are six M16 cable gland knockouts located
under the mains input socket. Using a blunt object, knock out the metal discs and insert M16 cable gland(s),
these can then be numbered or marked up accordingly.
