Safety First ..............Don't assume anything............. Always double check.

If in doubt, ask someone who is QUALIFIED to assist you in the subject.

Warnings

Please carefully read this manual and all warnings. Install the meter

ONLYwhen you are sure that you’ve covered all aspects.

Check that the model number and supply voltage suit your application

before you install the meter.

Connect the meter according to current IEE regulations, IEC61010 &

NFPA:70 National Electric Code in USA.

This meter is for Installation class II service only. This means it

has exposed electrical and power terminals. You must install it in

a suitable fire enclosure which will also protect users from electric shock

We designed this meter for Pollution-Degree 2 environments only.

It is sealed to IP65 NEMA4 from the front only.

Power supplies to this equipment must have anti-surge (T) fuses at

315mA for 230V supply, 315mA for 110V supply or 2A for DC supplies

in the range 11-30VDC. Aswitch or circuit breaker, clearly marked as a

disconnecting device, must be included close to the installation.

Don’t touch any circuitry after you have connected the meter, because

there may be lethal voltages on the circuit board.

Only adjust on-board switches or connections with the power turned off

Make sure all screw terminals are tight before you switch the meter on.

Only clean the meter’s front with a soft damp cloth. Only lightly dampen

with water. Do not use any other solvents. The behind-panel case may

be cleaned with a dry cloth only, use no liquid or solvent on it.

General Description

This series of meters accept industrial sensors to allow various physical

measurements to be made, such a weight, temperature, pressure, humidity

etc. Different models are available for different sensor types.

The main function of this series is to give a numeric readout of the variable

being monitored. Most models include an excitation power output, to power

the sensor directly.

Various optional output modules are also available to give alarm relay outputs,

analogue output or digital communications, or any combination of these options.

Meters are programmed using front panel pushbuttons. The buttons may be

locked with a rear switch.

Meters have two power supply options : 100-240 VAC or 11-30VDC

These meters are designed to mount into a protective enclosure which will

protect users from contact with power and signal wiring.

These units must be installed fully assembled, and must be installed according

to local electrical installation rules. When properly installed, they provide ingress

protection to IP54 from the front

Safety

Obey all safety warnings in this manual, and install the meter according to local

wiring and installation regulations. Failure to follow these guidelines may cause

damage to the meter, connected equipment, or may be harmful to personnel.

Any moving mechanical device controlled by this equipment must have suitable

access guards to prevent injury to personnel if the meter should fail.

!

Caution: There is a risk of electrical

shock if this instrument is not properly installed

Caution: Risk of danger: Read the whole

Wiring Advice

This meter uses detachable screw terminal connectors. Refer to the wiring

diagram on the following page for the correct positioning of each wire.

The conductors you use must be suitable for the meter’s temperature, current

and voltage rating, which is broadly described as follows:-

Cable Temperature Rating

All cables must be rated for operation up to 90C continuous.

Cable gauge and screw tightness

The connectors on this instrument can accept conductors up to 16 gauge

AWG / 1.5mm2c.s.a. The minimum cross sectional area shall be 22 gauge

AWG / 0.5mm2 . Tighten screw terminals to 7.0 lb/in torque / 0.8 Nm torque.

Cable insulation voltage rating

Cables shall have an insulation voltage rating of at least 380V continuous.

Wire preparation:

We recommend multi-strand wire, because it withstands vibration better than

single strand cable. Pull the wire firmly after you make the connection to confirm

it is tight.

Use screened cable for all signal and control wiring and connect the screen to

earth at the destination end only. Route signal cabling away from power cabling

and relay switching cabling, to avoid electrical noise interference.

No bare wires exposed

If you want to open your meter to install or modify option boards, follow these steps...

1) Switch off power to the meter and unplug all connectors.

2) Remove the 4 small screws shown in the diagram.

4) Slide the electronic boards out throught the rear of the case. The upper option board plugs

into a female socket on the main board. It is held securely in place with two option supports,

which have a grooved slot, into which the board sits.

To add or remove an option board, you must release the

screws holding the option supports, so that the option board

can be plugged into the socket. Then tighten the option

supports to clamp the option board firmly in place.

The board assemblies will look something like this...

The analogue output and RS232 or RS422 plug-in option boards are fixed to the upper option

board with white plastic pillars. You must apply a firm force when fitting or removing these options.

Always be careful to connect the pins to sockets accurately. When reassembling, make sure

option boards are firmly fixed to the upper option board.

The analogue output board plugs onto the 0, 2 or 4 alarm upper option board.

It plugs onto a pair of connectors and is secured by two snap-pillars.

Check that the unit is set for voltage or current output, to suit your application.

Re-assemble the meter, apply power and follow the Analogue Output Settings procedure on the

next page.

You can set the analogue output to operate over a display range of your choice, to create 0-

20mA, 4-20mA or 0-10V, fully isolated.

Please see the following page for a guide how to do this.

Handy Feature

You can tell if an analogue output is fitted to your meter, and if it has been set for voltage or

current, by viewing the ‘Summary’ display.

To see this, press the two outer buttons of the display for 3 seconds. You will also see the

You can have 3 types of alarm board:-

a) An alarm board with no relays, which will simply allow you to fit analogue and/or

serial output options.

b) An alarm board with 2 relays, to which you can also fit analogue and/or serial

output options.

c) An alarm board with 4 relays, to which you can also fit analogue and/or serial

output options.

For failsafe operation (where contacts open on alarm or when power is lost to the meter) set the

jumpers for OPEN CONTACTS as shown below, and DE-ENERGISE on alarm, in the alarm

setup menu.

To access the alarm board, remove power from meter, including any power which might be on

the alarm output board.

Look on the top and bottom surfaces of the case, near the rear. You will see two small screws,

one on each surface. Remove both screws. Now, clip off the front bezel and slide the meter

assembly carefully out via the front of the case.

The relay board plugs into the main board. Gently separate the two boards.

When you have set the jumpers, refit the board to the meter and carefully slide the

assembly back into the case.

Fit the two small screws to the top and bottom surfaces of the case.
