Installation Precautions

4 Read these instructions before using the gauge. Configuration may

be easier before installation. Contact the factory for assistance.

4 These products do not contain user-serviceable parts. Contact

us for repairs, service, or refurbishment.

4 Gauges must be operated within specified ambient temperature

ranges.

4 Outdoor or wash down applications require a NEMA 4X

gauge or installation in a NEMA 4X housing.

4 Use a pressure or vacuum range appropriate for the application.
4 Use fittings appropriate for the pressure range of the gauge.
4 Due to the hardness of 316 stainless steel, it is recommended

that a thread sealant be used to ensure leak-free operation.

4 For contaminated media use an appropriate screen or filter to

keep debris out of gauge port.

4 Remove system pressures before removing or installing gauge.
4 Install or remove gauge using a wrench on the hex fitting only.

Do not attempt to turn gauge by forcing the housing.

4 Do not exceed relay current and voltage ratings. Use an appro-

priate contactor for larger loads. Inductive inrush currents may
be up to 5x normal current and may require an RC snubber.

4 Good design practice dictates that positive displacement liquid

1

pumps include protection devices to prevent sensor damage
from pressure spikes, acceleration head, and vacuum extremes.

 Avoid permanent sensor damage! Do not apply vacuum to

2

non-vacuum gauges or hydraulic vacuum to any gauges.

 Avoid permanent sensor damage! NEVER insert objects into

gauge port or blow out with compressed air.

 Gauges are not for oxygen service. Accidental rupture of

sensor diaphragm may cause silicone oil inside sensor to
react with oxygen.

 NEVER connect the gauge wires directly to 115 VAC or per-

manent damage will result.

DPG1000ADA Series Digital Pressure Gauges With Alarms

Types of Gauges

Gauge reference models read zero with the gauge port open.
Compound ranges read vacuum in inches of Mercury, pressure

in psig, and zero with the gauge port open.
1000 psi and higher sensors are a sealed-reference type. They

read zero with the gauge port open are internally referenced to

14.7 psi. They function like gauge reference sensors.
Absolute reference gauges read zero at full vacuum and atmo-

spheric pressure with the gauge port open. Note that readings
of atmospheric pressure vary continuously.

Gauge Power Connections

The 2-conductor cable RED and BLACK leads is for the gauge
power supply. Note the relay cable also has red and black wires.
Do not connect power to them.

Connect to 8-24 VAC, 50/60Hz or 9-32 VDC. The gauge will
operate on either AC or DC power, either polarity. An unregu­lated power supply can be used. Note that 24 VAC transformers
with small loads may operate at voltages over the 24 VAC limit.
The supply voltage, when within the stated ranges, has negli­gible effect on the gauge calibration. Operation below 9 VDC
or 8 VAC may cause erratic or erroneous readings or output.

When operating multiple gauges from the same power supply,
refer to the mA rating in the specifications to ensure adequate
power. Route the wires away from heat sources and moving
equipment.

Power Up

The gauge is powered on whenever a supply voltage is applied.
Warm-up time is negligible. The gauge may be left on at all times.
All configuration information is stored in non-volatile memory.

When power is first applied, the gauge proceeds through a
startup sequence. During the startup sequence, relays are de­energized and the status LEDs are off.

1. The firmware version number is displayed briefly

2. All active display segments are turned on for approx. 1 second.

3. The full scale pressure is indicated for approx. 1 second while
the engineering units and FS (full scale) are indicated for 1/2
second on the character display.

4. The display is tested again for approximately 1 second.

The gauge then proceeds to the normal operating mode.

Alarm Contact Rating and Protection

The alarm contacts are rated at 1A/24VDC or 0.5A/115VAC.
Using mechanical relay contacts above their rating, or with large
inductive loads, will shorten their life. For inductive loads, RC
snubbers or arc suppression devices are required to protect the
contacts. For large loads a higher capacity contactor is required.

No internal fusing is included in the alarm contact circuits. The
alarm outputs should be externally fused by the user in applica­tions where good design practice dictates.

Alarm Types

The factory default configuration is 1% fixed deadband mode,
zero tare enabled, and no pass code required for test function.

Alarms may be configured to operate in fixed deadband mode
or adjustable hysteresis mode.

In the fixed deadband mode, the alarm set/reset point deadband
is factory set to 1% of full-scale. Each alarm may be configured
as either HI or LO with a user adjustable alarm set point for
each relay.

In the adjustable hysteresis mode, two independent set and
reset trip points are user adjustable for each relay. The set
or reset state at power up when between trip points is user
configurable.

Gauge Configuration

From the normal operating mode, press and hold the TEST and
s buttons.

Then press the SEL button.
Release all buttons when the display indicates CFG.

Before the gauge enters the Configuration mode, the display
initially indicates _ _ _ _ with the first underscore blinking,
and CFGPC on the lower display.

Enter the pass code as described below.

Pass Code Entry

A pass code is required to configure the gauge. Additional levels
of security may be enabled by defining separate pass codes
for calibration, configuration, output test, and set point adjust
modes. See Changing the User-Defined Pass Code at the end of
this manual to change pass codes.

Functions in user configuration mode
Restore original factory configuration
Enable/disable zero tare function
Choosing 1% deadband or adjustable hysteresis alarm mode
Operation for blinking alarm LEDs
Set point modes (high alarm/low alarm or state at power-up)
Relay action mode (normal/reverse)
Enable/disable pass code for output test and set point adjust

When the gauge requests a pass code, the display indicates

____ with the first underscore blinking, and either TSTPC,
CFGPC, CALPC on the lower display. All three pass codes

are initially set to the factory default of 3510.

Note: During pass code entry the LEDs will be off and the gauge
will not respond to changes in pressure. The relays will maintain
their prior state. The gauge will automatically revert to the nor­mal operation if no buttons are ressed for approx.y 15 seconds.

Use the s and t buttons to set the left-most digit to 3.

Press and release the SEL button to index to the next position.
The 3 will remain, and the second position will be blinking.

Use the s and t buttons to select 5.

Press and release the SEL button to index to the next position. 3
5 will remain, and the third position will be blinking.

Use the s and t buttons to select 1.

Press and release the SEL button to index to the next position. 3
5 1 will remain, and the fourth position will be blinking.

Use the s and t buttons to select 0.

Press and release the SEL button to proceed.

If an incorrect pass code was entered, the gauge will to exit to
the normal operating mode. Upon successful pass code entry,
follow the steps in the appropriate section of this manual.

Note: To exit a mode at any time, press and hold the SEL button
until the display indicates – – – – .

Restore Factory Configuration

The upper display will be blank, and the lower display will
display either USER_ or FCTRY.

Use the s or t buttons to select either USER_ or FCTRY.
If USER_ is selected, the existing user configuration will be

retained and can be modified in the following steps.
If FCTRY is selected, the existing user configuration will be

replaced with the factory configuration. It can be modified in
the following steps.

When the desired setting is displayed, press and release the
SEL button to move on to the next parameter.

Zero Tare Configuration

The upper display will be blank, and the lower display will
indicate either ZTARE or NOZTR.

Use the s or t buttons to select either ZTARE or NOZTR
If ZTARE is selected, the user will be able to manually zero

the gauge from the normal operating mode.
If NOZTR is selected the user will be prevented from zeroing

the gauge from the normal operating mode. This is default set­ting for absolute reference ranges.

When the desired setting is displayed, press and release the
SEL button to move on to the next parameter.

Alarm Type Selection

The lower display will either indicate DBAND or ADJ_H.
If DBAND is selected, each relay will operate with 1% of full-

scale deadband between set and reset.
If ADJ_H is selected, each output relay will have an adjust-

able set point and an adjustable reset point.
Use the s or the t buttons to select either DBAND or

ADJ_H.

When to desired mode is displayed, press and release the SEL
button to move on to the next parameter.

LED Alarm Annunciator Function Selection

This setting lerts the operator to an alarm conditionby blinking
the LEDs. The choices are
Automatically acknowledge: A_ACK
Manually acknowledge: M_ACK
No acknowledgement: NO_AN

Use the s or t buttons to cycle through the three choices.
A_ACK: An alarm condition will be automatically acknowl-

edged when the alarm condition clears. When an alarm condi­tion occurs, the LED for that alarm will begin to blink red until
it has been manually acknowledged by a pressing the TEST
button, or until the alarm condition no longer exists. If an alarm
is manually acknowledged, the LED will be steadily red while
the alarm condition continues to exist. The LED will be steadily
green whenever no alarm condition exists.

M_ACK: An alarm condition must be manually acknowledged.
When an alarm condition occurs, the LED for that alarm will
blink red if the alarm condition exists or blink green if the alarm
condition no longer exists. The LED will continue to blink until
it has been manually acknowledged by a pressing the TEST
button. Once an alarm has been acknowledged, the LED will be
steadily red while the alarm condition exists or green when the
alarm no longer exists.

NO_AN: The LEDs will not blink. When an alarm condition
occurs, the LED associated with that alarm will be steadily red
if the alarm condition exists, or green if the alarm condition
no longer exists. In addition, the LCD display for ALARM1 and
ALARM2 will not be displayed during alarm conditions.

When the lower display indicates the desired annunciator
action, press and release the SEL button to move on to the
next parameter.
