Introduction

The Druck DPI 104 is a digital pressure indicator that measures the pressure of liquid, gas or vapour and shows the pressure value on a liquid crystal display (LCD). It also has the Intelligent Digital Output Sensor (IDOS) technology to use data from a Universal Pressure Module (UPM).

The DPI 104 includes these functions:

Function

* Measure pressure - Accuracy: 0.05% full scale (FS)

Large 5-digit main display with 11 pressure units

Adjustable Full Scale Output (FSO)

20 segment analogue dial in increments of 5% FSO (large division marks = 10% increments).

2.5 digit percentage indicator (0-100% FSO)

8-pin connector port: For RS232, **IDOS UPM, external power supply

Alarm output for high/low pressure conditions

Switch input to monitor an external pressure switch

Analogue voltage output (Vout): 0 - 5 Vdc

Other functions: Maximum/minimum, tare, Vout scale factor, automatic power off

*Refer to “Specification data”.

**Optional item

Safety

Before you use the DPI 104, make sure that you read and understand all the related data. This includes: all local safety procedures, and this publication.

WARNING

•Some liquid and gas mixtures are dangerous. This includes mixtures that occur because of contamination. Make sure that the DPI 104 is safe to use with the necessary media.

•It is dangerous to ignore the specified limits for the DPI 104 or to use the DPI 104 when it is not in its normal condition. Use the applicable protection and obey all safety precautions.

•To prevent a dangerous release of pressure, isolate and bleed the system before you disconnect a pressure connection.

•Do not use the DPI 104 in locations with explosive gas, vapour or dust. There is a risk of an explosion.

Before you start an operation or procedure, make sure that you have the necessary skills (if necessary, with qualifications from an approved training establishment). Follow good engineering practice at all times.

To start - Prepare the instrument

Before you use the instrument for the first time:

•Make sure that there is no damage to the instrument, and that there are no missing items.

•Install the battery (refer to “Installation”). Then re-attach the display bezel [A1: item 6].

To start - Power on or off

Press the buttons in the sequence shown below.

• Power on sequence:

1			First display =	Then:
			FS limit	Normal output

• Power off sequence:

Normal output 1 Menu: 2

OFF

(For 2 seconds)

When the power is off, the last set of configuration options stays in memory.

Note: The DPI 104 uses a small quantity of power while it is OFF. If you put it into storage for a long period, disconnect the battery (refer to “Installation”).

Monitor function is set on or off

Monitor function is set on or off

C0 (Correct the zero offset value)

C2 (Do a two-point pressure calibration)

V2 (Do a two-point voltage calibration). Refer to “Calibration”.

On 000.0 ↓ 100.0 ↑

Set a value for the low and/or high alarm (0 to 105% FSO).

US 000.0: Set a Vout value (0 to 100%) to control an external pressure regulator. Make sure the Vout scale factor is correct.

If applicable, set a new Vout scale factor (0.01 to 9.99). Factory value = 1.00

On Au 15 : Set the period for automatic power OFF (1 to 99 minutes). Factory value = 15 minutes.
