Due to variations in the ambient (temp. and R.H.) zero calibration must be initially and
periodically checked to assure best performance. (See Calibration Section)

11. After selecting from the above, the LCD will show a new mode (SETUP, etc.) and the MAN,
ZERO and TEST push-buttons will have new functions.
Refer to Figures 2 and 5 before proceeding
a.
Auto Calibration
(Optional) select JP-2, LCD shows ACON. Haloguard
TM
compares temp.
and RH every 4 hours to compensate for changes in ambient.
b.
Scan Rate
- Rate is factory set at 4 sec. per active channel. To change, select JP-3, push
ZERO or TEST and step to desired rate. Remove jumper from JP-3.
c.
Channel and Gas Type
- See
Figure 10 - Initial Factory Setting
for channel set-up. To
change, select JP-4. Press ZERO or TEST and sequence to channel (1 thru 6) desired. Press
MAN to initiate gas type menu. Press ZERO or TEST and scroll to gas type desired (Note:
“None” selected will skip channel). Proceed to next channel and follow same process. When
finished, remove jumper from JP-4.
d.
Relay Latch Setup
- Recommended factory setting is Unlatched Mode; the alarm LEDs and
relays will return to a normal status when gas concentration goes below alarm set point. To
select Latched Mode place jumper on JP-8. Press RESET button to release alarm or check
for false alarm (Note: Alarm will be disengaged for 20 minutes).
e.
Audible Alarm
- JP-9 is factory installed to activate alarm circuit. To silence alarm remove
JP-9 jumper.
12.
TWA Integration
, (Optional). Haloguard
TM
calculates an 8 hr.
TLV-TWA,
displays this value
on LCD, activates LO alarm LED and relay if preprogrammed PPM value is exceeded.
(
Haloguard
TM
must be powered up for 8 hrs. to build database before operating).
13. Trim optional analog outputs by entering TEST mode (See
TESTING
) and turning
potentiometers on AN 1 thru AN 4 (see Figure 2 Upper Circuit Board) until output measures
5.0 or 10.0 VDC as required.
CALIBRATION
1. The Haloguard
TM
has been factory calibrated under standard conditions (70
o
F, 65% R.H.).
Due
to variations in the ambient (temp. and R.H.) zero calibration must be initially and
periodically checked to assure best performance.
