The instrument is provided with a USB interface for direct connection to a PC. Free software USBSpeedLink is available, is simple to use and provides the user with either basic or advanced display modes. Please refer to the USB SpeedLink software for further information on configuration. The software can be downloaded.

Always remove battery before any wiring takes place. Gain access for connection and battery holder by twisting cap to release front panel assembly from case. For connection information please refer to the internal markings found on the protection panel.

The pressure sensor is pre wired to the STATUS INSTRUMENTS DM670PM assembly and is not user serviceable; the instrument should be returned to the supplier for replacement of a damaged or faulty sensor. Observe safety precautions when mechanically mounting the STATUS INSTRUMENTS DM670PM; material and mechanical specifications are available in the DM670PM data sheet.

Two independent change over contacts are provided. Screw terminals are provided for connection for wire size 16 to 20 AWG. All cable entries must be sealed to at least IP65 rating. The relay contacts are rated at 48 V dc 28 V ac rms @ 1 A (5 mA minimum current) see DM670PM data sheet.

To remove the battery use a screw driver to ease the positive end of the battery out of holder. Insert new battery negative end first then press into place. Observe polarity. Battery type is 3.6 V Lithium (2.4 A/Hr) CR14505 (IEC) AA case style. Please dispose of the battery in a responsible way.

The display layout provides the following:

1. NFC – The Symbol is on when a NFC field is detected. When a detected field is lost the symbol will turn off after a few seconds.

2. TRANSMIT/RECEIVE – Symbol on when either NFC or USB communication is active.

3. OFFSET MODE – The centre circle with the outside bars will show when an input offset has been applied if the DM670PM is in offset mode.

4. USB – Symbol on when USB port is connected to a PC. Please note battery is not required during configuration.

5. LOG and 7. BAR GRAPH – These two symbols indicate the state of the logger. The condition is dependent on the selected logger mode either single or Rolling mode.

6. BATT – Symbol on when low battery is detected.

8. DEG – When the temperature display option is selected, degree Symbol used to indicate either °C or °F on the last digit.

9. DIGITS – Six digit 14 segment display with – sign, range 9999.9 to -9999.9. Advanced mode offers two temperature dependent 32 character message options.

10. WARNING ICON – This symbol will toggle on and off to indicate a warning. The warning symbol will be active either when the sensor signal is out of range, not connected or when the battery is low.

In Single Mode (Log to the maximum number of logs then stop):

LOG – symbol is off when not logging. On when logging. Flashing when full.

BAR GRAPH – Indicates the log volume.

The sequence of indication across the log volume during operation is:

In Rolling Mode (Log to the maximum number of logs then as each new log is taken the oldest log is discarded):

LOG – symbol is off when not logging. On when logging. Flashing when full.

BAR GRAPH – Indicates the log volume Toggling on/off when log has rolled over.

The sequence of indication across the log volume during operation is:

The alert LED normal state is off. On alert the LED will emit an intense white light pulse every 5 seconds. The LED can be programmed to pulse on any of the following combined events:

In advanced mode only the alert LED can be made to alert in any one of eight user set temperature bands. Example to alert operator when temperature is outside a safe operating range. The function of the alert LED can be further enhanced with the option of displaying an alert message in advanced display mode.

This button allows the user to display recorded pressures with or without time stamp dependent on the option selected by the configuration software:

Active: The maximum, minimum pressures. (Factory default setting)

Timestamped: The maximum, minimum, average and current (now) pressures with time stamps, format “day”+ “date” +”month” +”Year” + “time” (see note *1).

To clear maximum/minimum/average data press and hold the max/min button, the alert LED will pulse, after 3 short pulses the LED will give a longer pulse. Keep the button held on until the last pulse goes out. The data and time stamps will now be cleared.

Offset: Will set the instantaneous value of the input to zero or a pre-set value (defined in the configuration software), the offset icon will be displayed.

To clear the offset press and hold the offset button, the alert LED will pulse, after 3 short pulses the LED will give a longer pulse. Keep the button held on until the last pulse goes out. The offset will now be cleared and the offset icon will go out.

Note: caution is required if using the offset function when a user custom(x, y) profile has been entered.

This button allows the user to display the relay state with or without a time stamp dependent on the option selected by the configuration software:

Timestamp off: Relay 1(2) Title, State, Action, Set point. (Factory default setting)

Timestamp on: Relay 1(2) Title, State, Action, Set point, last trip on time date, last trip off time date, format “day” + “date” + “month” + “year” + “time” (see note *1).

To clear latched relay(s) press and hold the relay button, the alert LED will give 4 short pulses. Keep the button held on until the last pulse goes out. The latched relays will now be cleared (as long as the alarm condition has also cleared).

In the case of latched relays the time stamp will apply to the latch set and clear.

The NFC interface allows the instrument to communicate with an Android device using NFC connectivity.

The prime function of the interface is to read logged data from the device using a free app, which is available for downloading to Android devices. The app allows the user to read existing logs, change the log manifest, start a new log, synchronise the instrument clock and reset the maximum/minimum/average readings. Logs can run to a fixed number and stop or continually roll over, up to 5000 log points can be recorded. The start of the log can be delayed up to one month.

Note: For larger logs the data may take over a minute to fully download via the NFC interface.

The USB interface allows the instrument to communicate with a PC running the USBLogLink software.

The prime function of the interface is to read logged data from the device using free software available to download. The software allows the user to read existing logs, change the log manifest, start a new log, synchronise the instrument clock and reset the maximum/minimum/average readings. USBLogLink is available from the manufacturer or supplier.

Note *1 The time stamp requires the instrument real time clock time date to be maintained when the battery is replaced (no summertime daylight saving function is enabled), this can be done via the NFC interface app or the USB configuration software.

The instrument is a high accuracy digital pressure meter. In order to ensure correct operation the following must be observed:

The product must be stored in a dry clean environment and remain in original packaging prior to installation.

The instrument must not be installed adjacent to electro mechanical starters, controllers, thyristor power units or electrical switch gear.

Any cleaning of the instrument must be done using a mild detergent and soft cloth. No solvents or abrasive cleaners should be used.

Any external cable entries must be sealed to at least IP65 rating.

Stated ambient operating conditions must not be exceeded. Battery life will reduce with higher ambient temperature operating conditions.

For a wiring diagram please refer to the rear panel of the STATUS INSTRUMENTS DM670PM inside the case housing. 2 part connectors are used for both relay connections, allowing the unit to be easily removed from the housing for reprogramming or data download if this is not possible in situ.

Case notes: one M16 blanking plug is provided with each housing.

Case style L wall mounted versions are secured using three equally spaced 5.0 mm Dia holes, on a 114.5 mm dia circle.

The enclosure must be sealed to at least IP65 rating to ensure correct operation of the electronics. Care must be taken when installing assembly to ensure the stated ambient operating conditions are not exceeded. Material: Enclosure Stainless steel. Front panel membrane polycarbonate.

There is a low battery alarm available on relay 2 only.

The diagrams illustrate the behaviour relative to the Set Point (SP) and Deadband (DB) for different relay trip conditions (High Alarm, Low Alarm, High Control, Low Control, Trip outside band, Trip inside band). The Relay On and Relay Off diagrams specifically show the state of the relay output relative to these set points for control action.
