Instruction 3015-4286

Viewing the Fault Log

From the

Data Display

screen, use the

Keypad

buttons to place the arrow (>) on the display next to the

FAULTS

function. Then press

ENTER

to display the fault log.

The fault log shows the monitor’s current fault status. If the fault is still present
when the

FAULTS

function is selected, then the current cause of the fault is

displayed along with the date and time it occurred. If the cause of the fault has
been cleared, then the fault log will show <0000> along with the date and time
the fault was cleared. Use the

keypad

buttons to scroll through the fault log. In

the examples shown to the left, record #03 shows that a Zone Flow Fault (fault
code <0800>) occurred on 11/12/03 at 08:17, while record #04 shows that the
fault was cleared on 11/12/03 at 8:30.

The cause of the fault is identified by a numeric fault code. To convert the fault
code into a text description of the fault, first press the

ENTER

button and then

use the

Keypad

buttons to scroll through the display until the text description of

the fault appears. If the fault code is a combination of two or more faults, then
continue to use the

Keypad

buttons until all fault text descriptions have been

displayed. For example, the fault code <1800> represents the combination of
both a Zone Flow <0800> and a Purge Flow <1000> fault as shown to the left.

Note that the Fault Log can be cleared as described in Section

Clearing the Stored PPM Log, Alarm & Fault

Data

(Page 20).

Fault Codes

FAULT CODES ARE ADDITIVE

. For example: A

fault code of <1800> indicates that both a Purge Flow
Fault <1000> and a Zone Flow Fault <0800> have
occurred

<0001> Box Temperature Fault:

Enclosure

temperature is outside normal range (or IR detector
has failed). Check that the monitor is not being
subjected to extreme temperatures. Verify that the
ventilation holes are not obstructed. Use the

DIAGNOS

function (Page 21) to check the Box

Temperature.

<0002> Bench Temperature Fault:

Optical bench is

outside normal operating range (or IR detector has
failed). Check that the monitor is not being subjected
to extreme temperatures.

<0004> - Manifold Pressure Fault:

The manifold

pressure is outside normal operating range (or IR
detector has failed). Enter the

DIAGNOS

function

(Page 21) and record ALL data. Call the factory with
this information for further instructions.

<0010> Loop Fault:

The 4–20 mA current loop is open,

or there is a high resistance in the circuit. Check the
wiring to the load/monitoring circuit. If this feature is not
being used, a 100 ohm resistor must be connected to
the 4–20 mA connector (Page 11).

<0100> Zero Filter Fault:

There is refrigerant gas

present in the purge air. Locate the monitor in an area
containing fresh air, or install a purge air line. Refer to

Location of the

Monitor (Page 5).

<0200> Gain Set Fault:

The digipot autotune

sequence has failed. This fault will only occur on first
boot up or after a firmware upgrade. Call the factory
for further instructions.

<0400> A/D Fault:

A fault has occurred in the

analog-to-digital circuitry. Contact the factory with this
information for further instructions.

<0800> Zone Flow Fault:

Check for: A kink in the

gas-sample line or exhaust line; a blocked external
termination filter; a blocked internal hydrophobic filter
(Page 8); a failed pump.

<1000> Purge Flow Fault:

Check for: A kink in the

purge line; a blocked external termination filter; a
blocked internal hydrophobic filter (Page 8); a failed
pump. Once the blockage has been cleared, the
monitor will return to normal operation after the
monitor completes a purge cycle.

<4000> Zero Fault:

The IR detector’s output voltage

is out of tolerance. Enter the

DIAGNOS

function

(Page 21) and record ALL data. Call the factory with
this information for further instructions.

<8000> Clipping Fault:

The detector voltage may be

out of tolerance. Use the

DIAGNOS

function

(Page 21) to check the IR detector voltage. Call the
factory with this information for further instructions.
