Thank you for choosing the Temperature Controller. This User Guide takes you through step by step instructions to help you to install, wire, configure and use the controller. The ordering code is shown on a label fixed to the side of the controller. The hardware installed and the way in which it has been configured may be checked against the ordering code at the bottom of this page.

Step 1: Installation This instrument is intended for permanent installation, for indoor use only, and enclosed in an electrical panel Select a location which is subject to minimum vibrations and the ambient o o temperature is within 0 and 55 C 32 - F The instrument can be mounted on a panel up to 15mm thick To ensure IP65 and NEMA 4 front protection, mount on a non-textured surface.

Please read the safety information in section 4 before proceeding and refer to the EMC Booklet part number HA for further installation information. Panel Mounting the Controller Prepare a square cut-out in the mounting panel to the size shown Fit the IP65 sealing gasket, if required, behind the front bezel of the controller Insert the controller through the cut-out Spring the panel retaining clips into place.

Secure the controller in position by holding it level and pushing both retaining clips forward. Peel off the protective cover from the display 45 mm - 0. Dimensions 90mm 3. When plugging it back into its sleeve, ensure that the latching ears click back into place to maintain the IP65 sealing. HA Issue 1. Wire Sizes 3. Digital communications Optional 4. Hinged covers prevent hands or metal making accidental contact with live wires.

The rear terminal screws should be tightened to 0. Digital communications uses the Modbus protocol. The interface may be ordered as RS or RS 2-wire. Safety Symbols Various symbols may be used on the controller. They have the following meaning: 3. PV Input Measuring Input Do not run input wires together with power cables When shielded cable is used, it should be grounded at one point only!

The common connection is shared for each of these inputs and is, therefore, not isolated. Enclosure of Live Parts To prevent hands or metal tools touching parts that may be electrically live, the controller must be enclosed in an enclosure. Caution: Live sensors The controller is designed to operate with the temperature sensor connected directly to an electrical heating element. However you must ensure that service personnel do not touch connections to these inputs while they are live.

With a live sensor, all cables, connectors and switches for connecting the sensor must be mains rated. Thermocouple Input RTD Input For thermocouple input use the correct compensating cable preferably shielded The resistance of the three wires must be the same. The line resistance may cause errors if it is greater than 22? CT input resolution — 0. Take particular care not to connect AC supplies to the low voltage sensor input or other low level inputs and outputs. Only use copper conductors for connections except thermocouple inputs and ensure that the wiring of installations comply with all local wiring regulations.

Linear Input mA or V 3. A line resistance for voltage inputs may cause measurement errors For volts input an external module is required. Input resistance K?. For mA input connect burden resistor of 2. This device should be in close proximity to the controller, within easy reach of the operator and marked as the disconnecting device for the instrument. Power Supply Before connecting the instrument to the power line, make sure that the line voltage corresponds to the description on the identification label For 24V the polarity is not important The power supply input is not fuse protected.

This should be provided externally:? A OR Digital Input contact closure Voltage rating The maximum continuous voltage applied between any of the following terminals must not exceed Vac: relay output to logic, dc or sensor connections; any connection to ground.

The controller must not be wired to a three phase supply with an unearthed star connection. Under fault conditions such a supply could rise above Vac with respect to ground and the product would not be safe.

Instrument fuse ratings are as follows:- 3. Output 2 Relay or Logic Conductive pollution This is optional and is output only. It may be relay or logic output as output 1. Through the internal contacts, these transients may introduce disturbances which could affect the performance of the instrument.

A snubber will also prolong the life of the relay contacts. It is the responsibility of the installer to ensure that this current does not hold on the power to an electrical load. If the load is of this type the snubber should not be connected. TE10 Controller fuse Relay output fuse Electrically conductive pollution must be excluded from the cabinet in which the controller is mounted. For example, carbon dust is a form of electrically conductive pollution.

To secure a suitable atmosphere in conditions of conductive pollution, fit an air filter to the air intake of the cabinet. Where condensation is likely, for example at low temperatures, include a thermostatically controlled heater in the cabinet. Over-temperature protection Where damage or injury is possible, we recommend fitting a separate over-temperature protection unit, with an independent temperature sensor, which will isolate the heating circuit. Please note that the alarm relays within the controller will not give protection under all failure conditions.

When using relay outputs it may be necessary to fit a filter suitable for suppressing the emissions. The filter requirements will depend on the type of load. What happens next depends on whether the instrument is new or has been switched on before. For a new controller go to section 5. New Controller Unconfigured 5. To Re-enter Quick configuration Mode button during power up and then entering a passcode.

This enables you to configure the controller to match the process. The upper section of the display shows the set selected, the lower section shows the five digits which make up the set. Adjust these to suit your process as follows Press any button.

The first one flashing. Press or This mode can always be entered by holding down the defaulted to 4. The controller can be left to operate in this way. The 5. Normal Operation to scroll to the next character press 3.

Press configured in Set 1 the display will go to Set 2. When the last digit has been selected press controller will re-start. Now go to section 5. AUTO is the normal closed loop temperature control mode which means that the output power is adjusted automatically by the controller in response to the measurement from the input sensor. In this mode you will see the display shown below.

It is called the HOME display. OP2 lit when output 2 is ON normally cooling. To Acknowledge an Alarm. Press and together If an alarm is still current the red ALM beacon will flash, a scrolling message will give the source of the alarm and any relay attached to the alarm will operate.

When acknowledged, these functions will change as described in section 6. To Set The Required Temperature. Press to raise the setpoint, or to lower the setpoint — when the HOME display is being shown. The new setpoint is entered when the button is released and is indicated by a brief flash of the display. Manual operation The controller can be set so that the output power can be adjusted directly by the operator. This may be useful during commissioning or if the sensor becomes faulty and it is required to continue temporary operation of the plant until the sensor is repaired or replaced.

Manual operation must be used with care and the power level set must be chosen such that no damage can occur to the process. This is shown in the upper display and the MAN beacon is lit. The upper display is the PV.

The lower display is the demand power. Press or to raise or lower the power. These can be selected in Level 2. Dwell timer 2. Delayed switch on timer 3. Soft start timer There are four operating states, all of which are available in Level 1: Run may be initiated by pressing and together.

A dwell timer TI. The action which occurs at the end of the timed period depends on the configuration of the END. T parameter. End State e n d. End The above states may also be set by the following methods:? Edge trigger a suitably configured digital input?
