6.13 Bypass
The Bypass mode allows power to the enclosure to be energized when the enclosure pressure is below the
minimum pressure P1. This can be useful in commissioning the enclosure or working on the enclosure when
it is open.
The Bypass option has two modes of operation to choose from.
Mode Description
N No Bypass is not enabled.
Y Yes Bypass is implemented using the purge settings menu. By select-
ing ‘Y’, the system will go into bypass and will turn on K1. In the
‘Y’ mode, K1 can be energized before the system goes through a
successful purge. This mode can be useful in commissioning the
enclosure during start up. This mode is on when it is selected and
the menu stays in the purge settings mode. If the user exits from
the purge settings mode, then the Y’ is automatically changed to
‘N’ and K1 will de-energize.
Bypass LED is on.
Danger!
Bypass should only be implemented when the area surrounding the pressurized enclosure is known to be
non-hazardous!
6.14 Units
The units can be changed from ‘M’ metric to ‘I’ imperial. This affects the pressure readings. "M" reads in
mbar, and "I" reads in inches of water column. The temperature settings are always in Celcius.
