elements

See Figure 1 for location of elements:

Feature Description

Enclosure A polycarbonate box, approximately 7 x 5 x 3, with a detachable front cover.

4 holes for mounting the enclosure to a vertical surface. Located at the corners of the bottom

of the enclosure, directly beneath the 4 front cover retaining screws. See Figure 3

Input Port The entrance for the air sample and calibration gas. The quick release fitting mates with one

on the optional Sample air hose and the calibration adapter.

Front Cover

Detachable front cover of PID-G

UARD

with Display Panel. See Section 2.2 and Figure 1

There are 4 Screws that hold the front cover in place.

Sample Air Hose

(Optional)

A five foot long hose to conduct a sample of the air from the source to the instrument.

The hose has a Female quick release fitting and regulator. See Figure 1a

Regulator

(Optional)

To connect to the compressed air line. Sample pressure to the PID-G

UARD

should be set to

PSI

. See Figure 1a

Output Port Sampled air out: Luer connection provided to connect to tubing

2.2 PID-G

Operational Features

The Display Panel is attached by a cable and is released by unscrewing the 4 screws located in the corners. After releasing the

panel, it is swung upward, exposing the interior of the enclosure. See Figure 1 for location of features.

Feature Description

Display A single line, 8 character LCD with backlight. Indicates the level of gas detected by sensor.

The numerical value of gas concentration and other information is displayed.

Audio Alarm(Horn) Audio alarm (105 dB at 30cm/12in). The audio alarm is on when the unit is in alarm.

Visual Indicators and

Alarms

LED indicators:

Power / Fault Indicator LED, Green / Red

Alarm (3) Indicator LED, Red

Membrane Switches 2 Pushbutton Switches on front panel control the instrument maintenance functions. The

pushbutton switch locations are indicated by:

ENU

↓: Advances the instrument display through operation information and maintenance

menus

ELECT

: Disables audio alarm temporally and

Selects the maintenance menu operations such as, Zero, Span, Exit menu or sets

proper calibration values for Zero or Span

See Section 4.0 and 5.0 for operational and maintenance flow charts.

Flowmeter A flow indicator located at the output of the sample flow stream, which indicates

quantitatively the flow of sample air or calibration gas through the instrument.

Three alarm points are preprogrammed into the PID-G

UARD

. At each alarm point, an LED on the front panel is activated.

These internal alarm settings are independent of the 4-20mA output alarm values that can be set at a controller. An optional

relay board is available that will activate 0.5 Amp relay contacts at each alarm point, plus a fault relay.
