Chapter 1 Introduction To The Universal Process Amplifier System

The Mantracourt Electronics Universal Process Amplifier System is based upon a concept of modular construction. By
adopting such a concept, it is possible to offer a great deal of flexibility of construction, to meet the wide and
varying needs of system building.
The system is centred on a Eurocard sized amplifier PCB, which consists in its standard form of, Central Processing,
and voltage and current Analogue output ports. Facilities are provided to connect a series of ‘plug in ’ option boards
for inputs, relay and communications outputs together with mains and low voltage DC power supply options.
A special Fast Analogue output module is also available to complement a Fast Strain Gauge input option.
The modular concept offers the opportunity for assembly in Surface Mount, DIN Rail and 19-inch Rack variants.
The system concept is described in diagrammatic form with the range of options listed. The options will be
described under the various Chapters as follows:

1. Introduction

2. Installation requirements

3. Power Supplies

4. Input Modules

5. Output Modules & Communications Information

6. The Amplifier Displays

7. Programming the Amplifier including essential INPUT CALIBRATION ROUTINES, which must be actioned. See

Chapter 2 Installation

In order to maintain compliance with the EMC Directive 2004/108/EC the following installation recommendations
should be followed.

Inputs:

Comms Port:

Analogue
Output:

Use individually screened twisted multipair cable. (e.g. FE 585 - 646)
The pairs should be :
pins 1 & 6
pins 2 & 5
pins 3 & 4
Terminate all screens at pin 1 of the input. The screens should not be
connected at the transducer end of the cables.

Use individually screened twisted multipair cable. (e.g. FE 118-2117)
The pairs should be:

-Tx & +Tx

-Rx & +Rx
Terminate screens at pin 1 of the input .
The screens should not be connected at the host port.

Use screened twisted pair cable. (e.g. RS 626-4761)

Terminate screen at pin 1 of the input.
The screen should not be connected at the host port.

Pin 1 of the input should be connected to a good Earth. The Earth connection
should have a cross-sectional area sufficient enough to ensure a low

impedance, in order to attenuate RF interference.

Chapter 3 Power Supplies

There are three types of power supply available within the UAB system. The rack versions RUA1 and RUA2 are served
by a common power supply, which offers power to the 12 channels in the case of the RUA1 and 8 channels for the
RUA2. The Surface Mount versions are offered with mains an AC version or a low voltage DC version.

Section 1 - The Rack V ersion (RS1)

The RS1 supplies power to the channels within the rack via the common back plane, offering 220/240VAC at 50/60
Hz or 110VAC at 50/60 Hz. The 110/240 is selected by a switch on the rear of the power supply module. A green LED
on the front panel indicates when power is applied

A 5-Ampere protection fuse is fitted within the power input socket.

The maximum power rating for a full rack is 100 Watts.

Connection to the rack is made via a flying lead with a shrouded and earthed IEC mains connector

Note: Inputs are not intended to be connected to voltages above 50 VAC or 120Vdc

Tables 3.1 and 3.2 show details of the connections and voltages for the various supply rails.

Section 2 - The Surface Mount Versions (LS1 and LS3)

The LS1 power supply is a ‘plug in’ module supplying 110 Volts AC at 50/60 Hz or 220/240 Volts AC at 50/60 Hz.

A maximum power rating of 10 Watts is available, with this module.

The running current for each amplifier is between 250 and 480 milliamps dependant upon module configuration,
with a start up current of 3 Amps for 20 milliseconds. Earthing (or shield)- If the amplifier is not earthed elsewhere,
an earth should be made to the screen (SC) of the 15 way connector.

The LS3 module should be protected on installation by an in line fuse.

The LS3 power supply is a 'plug in' module supplying 9 to 30 Volts DC. Similar in characteristics to the LS1 with
regard to power and current ratings.
The module is not reverse polarity protected and will require similar protection at installation.

WARNING:
ENSURE POWER IS SWITCHED OFF BEFORE MAKING CONNECTION TO THE UAB

1. Connect the thermocouple to the UAB terminal as shown in Figure 4.6
Note: If the thermocouple has a floating input, connect terminal 1 to ground.

2. The external cold junction sensor is always connected between input terminals 4 and 6. If no external sensor is
used, link terminals 4 & 6.

3. Normally, thermocouple burnout is indicated by upscale over range. If downscale indication is required, link
terminals 2 & 3.

Note: It is recommended that 4 core-screened cable be used for this connection with terminal 6 used for screen and
ground.
If however, this is not practical, terminal 2 may be used for guard and ground.

UAFLC Fast Strain Gauge

The UAFLC offers a direct connection to most low level (foil) strain gauge sensors.
A 10-volt excitation is provided and it is monitored to compensate for any variation due to supply drift, load
regulation or voltage drop in the cable between the sensor and the UAFLC.
The maximum supply current is 150mA, which allows for the connection of 4 x 350 Ohm strain gauges.
Strain gauge sensitivity is preset via DIL switches to 0.5, 0.8, 1.0, 1.25, 1.5, 2.0, 2.5, 3.5, 5, 10, 20, 50, 100 and 200
mV/V. Select the next value higher than the strain gauge output maximum.

Note: It is important that the UAFLC is powered up with the strain gauge connected to the input as the A/D
performs an Autocal of its own on power up.
