Easy Tune

If the Controller is configured for Easy Tune operation, all tuning is performed automatically, at each power up.

Manual Tuning with Pre-Tune

If the Controller is configured for manual tuning, a one-shot Pre-Tune can be used to optimise system at any time.

NOTE: Pre-Tune is a single-shot operation and will automatically dis-engage itself after completion of its routine. Pre-Tune will not be activated; (a) if the process variable is within 5% of input span from the setpoint, (b) if the unit is configured for on/off control or (c) if Easy Tune is selected.

INSTALLATION

CAUTION: This equipment is intended for field installation within the enclosure of another product. Installation and configuration should be performed only by personnel who are technically-competent

& authorised to do so. Local Regulations regarding electrical installation & safety must be observed.

Panel Mounting

The mounting panel must be rigid and may be up to 6.0mm (0.25 inches) thick. The cut-out required for the Controller is shown on the right. Controllers may be mounted side-by-side in a multiple installation for which the cut-out width (for n Controllers) is (48n-4)mm or (1.89n-0.16) inches. For panel-mounting see below.

CAUTION: Do not remove the front panel gasket from the Controller, as this may cause inadequate clamping of the Controller to the mounting panel. Ensure that this gasket is not distorted and that the Controller is positioned squarely against the mounting panel. Apply pressure to the front panel bezel only.

MODBUS COMMUNICATIONS

Functions Supported

The following MODBUS functions are supported, (JBUS names - where such an equivalence exists - in italics):

Read Coil Status (Read n Bits) - 01/02 Read Holding Registers (Read n Words) - 03/04 Force Single Coil (Write 1 Bit) - 05 Preset Single Register (Write 1 Word) - 06 Loopback Diagnostic Test - 08 Preset Multiple Registers (Write n Words) - 16

The instrument will identify itself in reply to a Read Holding Registers message which enquires the values of parameter numbers 121 and 122.
