While holding the
TEST
button, use the
s
and
t
buttons to
adjust Set Point 1 to the desired value.
Release the
TEST
button to store the Set Point 1 value.
Note: The gauge will not respond to changes in applied pressure
while the
TEST
button is pressed. The alarm relays, LEDs, and
LCD alarm icons will maintain their prior states until the
TEST
button is released.
To exit the Set Point 1 Adjust mode and return to the normal
operating mode, press and release the
SEL
button.
Set Point 2
From the normal operating mode press the
SEL
button twice to
display Trip Point 2.
Press and hold the
TEST
button and press the
SEL
button.
Release both buttons when the display indicates – – – – .
If pass code setpoint protection is enabled, the display initially
indicates _ _ _ _ with the left-most underscore blinking, and
with
TSTPC
on the display. Enter the pass code as described
in the Pass Code Entry section.
If pass code setpoint protection is not enabled, the display will
indicate Trip Point 2 with
TRIP2
blinking at a slow rate on the
lower display, and the alarm indicators and the retransmission
output will correspond to the applied pressure.
Press and hold the
TEST
button. The display will indicate Set
Point 2 with
SP2
on the lower display.
While holding the
TEST
button, use the
s
and
t
buttons to
adjust Set Point 2 to the desired value.
Release the
TEST
button to store the Set Point 2 value.
Note: The gauge will not respond to changes in applied pres-
sure while the
TEST
button is pressed. The alarm relays, LEDs,
and LCD alarm icons will maintain their prior states until the
TEST
button is released.
To exit the Set Point 2 Adjust mode and return to normal opera-
tion, press and release the
SEL
button.
Operation: Adjustable Hysteresis Alarms
In the adjustable hysteresis mode, two independent set and
reset points used for each relay and operate as shown below.
The LEDs indicate green for a RESET state and red for a SET
state. Refer to the table for output states as a function of applied
pressure.
If the gauge is configured for alarms, ALARM1 and ALARM2 will
be indicated when alarm conditions exist, and the associated
Operation: Fixed Deadband Alarms
Each relay may be independently configured as a high or low
alarm in User Setup and operate as shown in the table below.
The relevant LCD alarm icon will indicate an alarm condition.
The relevant bi-color LED will be illuminated green for a normal
condition or red for an alarm condition.
The LED will blink at a slow rate until the alarm is acknowledged
unless the annunciator mode was disabled in setup.
Alarms may be configured to be automatically acknowledged
when the alarm condition clears or configured to be manually
acknowledged by pressing the
TEST
button.
Displaying Trip Points
The applied pressure, the value of Trip Point 1, and the value of
Trip Point 2 may be selected for display as follows:
When the applied pressure is being displayed, press and release
the
SEL
button.
The Trip Point 1 value will be displayed with
TRIP1
on the
lower display.
When the Trip Point 1 value is being displayed, press and
release the
SEL
button.
The upper display will indicate the Trip Point 2 value with
TRIP2
on the lower display.
Press and release the
SEL
button. The upper display will
indicate the applied pressure with engineering units on the
lower display.
Adjusting Setpoints: Fixed Deadband Alarms
Set Point is defined as the pressure value that will result in a
change of state only from a normal to an alarm condition.
Trip Point is defined as the pressure value that will result in a
change of state of alarm condition, and includes the effect of
deadband when returning from an alarm to a normal condition.
Set Point 1
From the normal operating mode press the
SEL
button to
display Trip Point 1.
Press and hold the
TEST
button and press the
SEL
button.
Release both buttons when the display indicates – – – – .
If pass code setpoint protection is enabled, the display initially
indicates _ _ _ _ with the left-most underscore blinking, and
with
TSTPC
on the display. Enter the pass code as described
in the Pass Code Entry section.
If pass code setpoint protection is not enabled, the display will
indicate Trip Point 1 with
TRIP1
blinking at a slow rate on
the lower display.
Press and hold the
TEST
button. The display will indicate Set
Point 1 with
SP1
on the lower display.
Relay Action in
DBAND
Fixed Deadband Mode
Use the
s
or the
t
buttons to select either
Normal Acting (Failsafe):
_NOR_
Reverse Acting:
_REV_
If
NOR_
is selected, the output relay coils will be energized in
the RESET state and de-energized in the SET state.
If
_REV_
is selected, the output relay coils will be de-
energized in the RESET state and energized in the SET state
When the desired alarm type is displayed, press and release the
SEL
button to move to the Output Test and Set Point Adjust Pass
Code Protection section.
Adjustable Hysteresis
ADJ_H
Alarm Setup
Relay Power Up State in
ADJ_H
Adjustable Hysteresis Mode
This determines the state of the relays if the gauge is powered
up while the pressure is between the SET and RESET trip points.
For some applications it may not be desirable to have an alarm
condition during power-up.
Use the
s
or the
t
buttons to select either
SP1_L
or
SP1_H
.
If
SP1_L
is selected and the gauge is powered up while the
pressure is between the Relay 1 SET and RESET trip points,
Relay 1 will begin in the RESET state.
If
SP1_H
is selected and the gauge is powered up while the
applied pressure is between the Relay 1 SET and RESET trip
points, Relay 1 will begin in the SET state.
When the desired alarm state is selected, press and release the
SEL
button to move to Relay 2.
Use the
s
or the
t
buttons to select either
SP2_L
or
SP2_H
.
If
SP2_L
is selected and the gauge is powered up while the
applied pressure is between the Relay 2 SET and RESET trip
points, Relay 2 will begin in the RESET state.
If
SP2_H
is selected and the gauge is powered up while the
applied pressure is between the Relay 2 SET and RESET trip
points, Relay 2 will begin in the SET state.
When the desired alarm state is selected, press and release the
SEL
button to move to the next parameter.
Relay 1 Action in
ADJ_H
Adjustable Hysteresis Mode
Press and release the
s
or the
t
buttons to select either
Normal Acting (Failsafe):
_NOR1
Reverse Acting:
_REV1
If
_NOR1
is selected, the output relay coil will be energized in
the RESET state and de-energized in the SET state.
If
_REV1
is selected, the output relay coil will be de-energized
in the RESET state and energized in the SET state.
When the desired Alarm 1 action is selected, press and release
the
SEL
button to move to Alarm 2.
Use the
s
or the
t
buttons to select either
Normal Acting (Failsafe):
_NOR2
Reverse Acting:
_REV2
If
_NOR2
is selected, the output relay coil will be energized
in the RESET state and de-energized in the SET state.
If
_REV2
is selected, the output relay coil will be de-
energized in the RESET state and energized in the SET state.
When the desired Alarm 2 action is selected, press and release
the
SEL
button to move to the next parameter.
Output Test & Set Point Adjust Pass Code
Protection
This setting determines if a pass code is required to acess the
Output Test and Set Point Adjustments.
Use the
s
or the
t
buttons to select either
TSTPC
or
NOTPC
.
The lower display will indicate
TSTPC
to enable Output Test
and Set Point Adjust Modes pass code protection.
The lower display will indicate
NOTPC
to disable Output Test
and Set Point Adjust Modes pass code protection, press and
release the
t
button.
Press and release the
SEL
button to save the configuration
parameters and restart the gauge.
