(Fixed Limit Relay)

Option Module 2

Mounting Struts

Option Module A

Option Module 3

PSU PCB

To access module A, first detach the PSU and CPU boards from the front by lifting first the upper, and then lower mounting struts. Gently separate the boards.

a. Plug the required option modules into the correct connectors, as shown below. b. Locate the module tongues in the corresponding slot on the opposite board. c. Hold the main boards together while relocating back on the mounting struts. d. Replace the instrument by aligning the CPU and PSU boards with their guides in the housing, then slowly push the instrument back into position.

Note: Option modules are automatically detected at power up.

Housing

Ratchets

Gasket

Slide mounting clamp over the instrument housing towards rear face of mounting panel until the tongues engage in ratchets and instrument is clamped in position.

Hold instrument firmly in position (apply pressure to bezel only)

CAUTION: Do not remove the panel gasket; it is a seal against dust and

moisture.

Rear Terminal Wiring

USE COPPER CONDUCTORS (EXCEPT FOR T/C INPUT)

Single Strand wire gauge: Max 1.2mm (18SWG)

Actual connections required depend on the options fitted.

CAUTION: Check information label on housing for correct operating

voltage before connecting supply to Power Input Fuse: 100 – 240V ac – 1amp anti-surge 24/48V ac/dc – 315mA anti-surge

2. SELECT MODE

Select mode is used to access the configuration and operation menu functions. It can be accessed at any time by holding down and pressing . In select mode, press or to choose the required mode, press to enter. An unlock code is required to prevent unauthorised entry to Configuration, & Setup modes. Press or to enter the unlock code, then press to proceed.

Note: At first power-up the message !"#" $"%& is displayed, (see section 6). Access to other menus is denied until configuration mode is completed

Notes: Output 1 is always a Latching Limit Relay output. If Option Slot A has the Digital Input module fitted, this always functions as a Remote Reset, duplicating the function of the Reset) key .

As these functions cannot be changed, no Configuration menus are required.

CAUTION: Process Variable Offset can be use to modify the measured

value to compensate for probe errors. Positive values increase the reading, negative values are subtracted. This parameter is effectively, a calibration adjustment and MUST be used with care.

There is no front panel indication of when this parameter is in use.

4. SETUP MODE

Note: Configuration must be completed before adjusting Setup parameters.

First select Setup mode from Select mode (refer to section 2). The Setup LED will light while in Setup mode. Press to scroll through the parameters, then press or to set the required value. To exit from Setup mode, hold down and press to return to Select mode.

Note: Parameters displayed depends on how instrument has been configured.

Exceed Condition

An Exceed Condition is when the Process Variable exceeds the Limit Setpoint value (i.e. PV > SP when set for high limit action, PV < SP for low limit action). The LED is on during this condition, and is extinguished once it has passed.

Limit Output Function

Limit Output relay(s) de-energise whenever an Exceed condition occurs, causing the process to shut down. The LED is on when the relay is de-energised. The relay remains latched off even if the Exceed condition is no longer present. Only giving a reset instruction (after

the exceed condition has passed) will re-

energise the relay, allowing the process to continue. The LED then turns off.

Limit Annunciator Outputs

An Annunciator output will activate when an Exceed condition occurs, and will remain active until a reset instruction is received, or the Exceed condition has passed. Unlike the Limit Output, an Annunciator can be reset even if the Exceed condition is present. When an Annunciator is active, the LED will flash and the Alarm Status screen is available.

Resetting Limit Outputs & Annunciators

A reset instruction can be given by pressing the key, via the Digital Input (if fitted) or via a Comms command if an RS485 Communications module is fitted. Annunciators will deactivate. Limit Outputs will only re-energise if the Exceed condition has passed.

CAUTION: Ensure that the cause of the Exceed condition has been

rectified before resetting the Limit Output.
