INTRODUCTION
System Hardware – Fig. 1.2
The 4680 and 4685 transmitters are part of the EXGP Oxygen
Analyzer System which measures oxygen content and
temperature within a gas flue. The system comprises an EXGP
oxygen probe, an interface electronics unit and a
4680/85 transmitter – see Fig. 1.2. Signals from the
transmitters can also be retransmitted to remote monitoring
equipment.
The 4680/501 model is a wall-mounted instrument and the
4685/501 model is a panel-mounted, DIN-sized instrument.
Both have a single programmable input channel and a single
temperature input channel.
Instrument operation and programming is via four tactile
membrane switches located on the front panel.
Programmed functions are protected from unauthorized
alteration by a five-digit security code.

ELECTRICAL CONNECTIONS
Warning.
• Mains power – before making any connections, ensure that the power supply, any high voltage-operated control circuits
and high common mode voltages are switched off.
4.1
Connections – General
Information.
• Earthing (grounding) – stud terminal(s) is fitted to the transmitter case for bus-bar earth (ground) connection – see Fig. 4.2 or 4.5.
• Cable routing – always route signal output cable leads and mains-carrying/relay cables separately, ideally in earthed metal
conduit. Twist the signal output leads together or use screened cable with the screen connected to the case earth stud.
Ensure that the cables enter the transmitter through the glands nearest the appropriate screw terminals and are short and
direct. Do not tuck excess cable into the terminal compartment.
• Relays –the relay contacts are voltage-free and must be appropriately connected in series with the power supply and the
alarm/control device which they are to actuate. Ensure that the contact rating is not exceeded. Refer also to Section 4.1.2
for relay contact protection details when the relays are to be used for switching loads.
• Retransmission output – Do not exceed the maximum load specification for the selected current retransmission range
(see the associated Specification sheet).
Since the retransmission output is isolated the –ve terminal must be connected to earth (ground) if connecting to the
isolated input of another device.
4.1.1
Cable and Gland Specifications
Caution.
• Cabling – connections between the Transmitter and the Interface Electronics Unit must be in accordance with BS5345 pt3
– Installation and Maintenance Requirements for Electrical Apparatus with type 'd' Protection Flameproof Enclosure.
• Glands – EEx d glands used on the Interface Electronics Unit must be of the EEx d 'Barrier Gland' type with BASEEFA
certification because the enclosure is over 2 liters volume, has a source of ignition within and is designed for use in Zone
1 areas (reference BS5345 part 3).

4.1.2
Relay Contact Protection and Interference Suppression – Fig. 4.1
If the relays are used to switch loads on and off, the relay contacts can become eroded due to arcing. Arcing also generates radio
frequency interference (RFI) which can result in instrument malfunctions and incorrect readings. To minimize the effects of RFI,
arc suppression components are required; resistor/capacitor networks for a.c. applications or diodes for d.c. applications. These
components can be connected either across the load or directly across the relay contacts. On 4600 Series instruments the RFI
components must be fitted to the relay terminal block along with the supply and load wires – see Fig 4.1
For a.c. applications the value of the resistor/capacitor network depends on the load current and inductance that is switched.
Initially, fit a 100R/0.022µF RC suppressor unit (part no. B9303) as shown in Fig. 4.1A. If the instrument malfunctions (incorrect
readings) or resets (display shows 88888) the value of the RC network is too low for suppression an alternative value must be
used. If the correct value cannot be obtained, contact the manufacturer of the switched device for details on the RC unit required.
For d.c. applications fit a diode as shown in Fig. 4.1B. For general applications use a 1N5406 type (600V peak inverse voltage
at 3A – part no. B7363)
✶
Note. For reliable switching the minimum voltage must be greater than 12V and the minimum current greater than
100mA.

Access to Secure Parameters
A 5-digit security code is used to prevent tampering with the secure parameters.
Enter the required code number between 00000 and 199999, to gain access to
the secure parameters. If an incorrect value is entered, subsequent

Set Point
The Set Point band is defined as the actual value of the Set Point plus or minus
the hysteresis value. The hysteresis value is fixed at 0.1% oxygen. Alarm action
occurs if the input value is above or below the Set Point band. If the input moves
within the Set Point band the last alarm action is maintained.
