Force On State (
ON
)
This alarm mode forces the output to be active, or on.
This mode is primarily used to test alarm systems.
Force Off State (
OFF
)
This alarm mode forces the output to be inactive, or
off. This mode is primarily used to test alarm systems.
Timer Output (
TIMER
)
The timer output produces a constant pulse width at a
constant frequency. Program the
Period
(
PERIOD
)
from 0.1 to 999999.9 seconds (time from the start of
one pulse to the start of the next pulse).
Program the
On Time
(
TIME
) for the active low pulse
from .01 to 99999.99 seconds (pulse width). The
on
time must be less than the delay time (Period).
Select
Start
(
START
) to begin outputting the constant
timed pulse.
Select
Stop
(
STOP
) to end outputting the constant
timed pulse.
Scaling the 4-20 mA Analog Output
(
Aout
)
The
Analog Output
menu is used to program the
4-20 mA output based on display values. This menu
is not present on models without a 4-20 mA output
option.
The 4-20 mA analog output (if equipped) can be
scaled to provide a 4-20 mA signal for any display
range selected for either Modbus PV 1 to 16 or math
channel CV 1 to 4.The output may be disabled (
DISA-
BLE
), and it will only output the minimum signal.
No equipment is needed to scale the analog output;
simply program two display values and corresponding
mA output signals.
Selecting the Analog Output Source
In the
Analog Output
(
A OUT
) menu, press the Enter
button. In the
Source
(
SOURCE
) menu, press the
Up
button to scroll through the menu choices.
Press
Enter
to make a selection and proceed to the
next menu.
