NOTE:
During the Parameter Setting Mode, normal unit
operation is suspended until this mode is exited.
No network communications, peripheral
communications, or alarm updates occur in this
mode. The current signal output will be equivalent to
a CAL signal of 3.75 mA.
When "END" displays, the Parameter Setting Mode
is complete and normal operation resumes.
•
If no key is pressed during the Parameter Setting Mode:
•
the unit returns to normal operation in one minute
•
any values that were accepted by using the CAL button
are saved.
When the unit returns to normal operation:
Use the MODE button to display and verify the settings.
Alarm Setting:
•
if the alarm is set to OFF (disabled):
•
latching status and value are not shown
•
once the upper limit is reached, the value rolls over to the
minimum value
•
for toxic and oxygen units:
•
the upper limit is the full-scale reading
•
for combustible units:
•
the upper limit is 60% LEL.
Method 2 - Ultima Controller
Parameters, alarm levels and their latched/unlatched modes of
operation are set and changed using an Ultima Controller
(P/N 809086). Refer to the Ultima Controller Instruction Manual
(P/N 813379) for full instructions.
Battery Backup
The Toxgard II Monitor can be configured with an (internal)
rechargeable backup battery that permits full instrument operation
if main power is interrupted or the Toxgard II Monitor is used as
a transportable instrument for temporary gas monitoring of an
area; the carrying handle and side-mount sensor are convenient
options if the Toxgard II Monitor is used as a transportable gas
monitor.
