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.
