OLCT 80
GAS TRANSMITTER
USER MANUAL
28 NPO80GB
Revision F.1
PG CH1
Purpose
Configure the
ANA1 sensor.
How to access
See Figure 21.
Tree structure
See Figure 23.
Menu Description
ON
Turn the
ANA1
sensor on or off.
PRINCIPAL
• Display
: display the reading from the
ANA1
sensor.
•
Primary
: display the reading from the
ANA1
sensor and go to the 4-20 mA menu (see step
below).
•
Secondary : the reading is not displayed.
Note: if multiple sensors (main sensor, ANA1 sensor or ANA2 sensor) are configured as the
Primary
, the -4-20 mA output will use the current corresponding to the
Main sensor
.
4-20 mA
Define the output current type (see the
Note on the 4-20 mA current type
on page 27).
•
Normal : standard 4-20 mA signal.
• Combined
: signal uses predefined values representing the alarm statuses of the 3 sensors.
This option is automatically selected if the
Secondary
option was defined in the previous step.
• CAPEX
: all-or-nothing signal indicating normal operation or a fault condition.
Measure
• Reading
: the channel will be used to input an analog reading (4-20 mA current only).
•
Acknowledge
: the channel will be assigned to a dry contact for remote acknowledgment
(function used only in the absence of the IR20 remote control). The contact will be wired
between the
S
and
E
terminals of the 4-20 mA input, labeled
IN1.
See Figure 5, 2 .
% LEL
Defines the unit of measure displayed on the LCD (%LEL, %O2, %, ppm H2S, ppm NH3, ppm
HCL, ppm CO2, ppm NO, ppm ETO, ppm H2, ppm HCN, ppm HF, ppm O3, ppm CLO2,
ppm, ppb, °C, V, hPa, [blank]).
Display
Define the position of the decimal point, e.g., 22.22.
Gamme
Define the reading range on the LCD (001-100 in increments of one, 100-1000 in increments
of ten or 1000-9900 in increments of one hundred).
Zero in V
Define the bottom of the range in volts.
0.48 V corresponds to 4 mA through a 120 ohm resistor.
Scale in V
Define the top of the range in volts.
2.40 V corresponds to 20 mA through a 120 ohm resistor.
Coef
Defines the reading integration time (none, 5 seconds, 30 seconds, 1 minute, 2, 5, 10 or 15
minutes). The reading will be averaged over the given period.
