1.3.1Mains (Line) Input

The Profile Controller will operate on 96 - 264V AC 50/60Hz mains (line) supply. The power consumption is approximately 4 VA. Power should be connected via a two-pole isolating switch (preferably situated near the equipment) and a 1A fuse.

If the Profile Controller has relay outputs in which the contacts are to carry mains (line) voltage, it is recommended that the relay contact mains (line) supply should be switched and fused in a similar manner but should be separate from the Profile Controller mains (line) supply.

1.3.224V (Nominal) AC/DC Supply

The supply connections for the 24V AC/DC option of the Profile Controller are as shown in Figure 1-4. Power should be connected via a two-pole isolating switch and a 315mA slow-blow (anti-surge Type T) fuse.

With the 24V AC/DC supply option fitted, these terminals will accept the following supply voltage ranges:

24V	(nominal) AC 50/60Hz -	20 - 50V
24V	(nominal) DC -	22 - 65V

1.3.3Thermocouple Input

The correct type of thermocouple extension leadwire or compensating cable must be used for the entire distance between the Profile Controller and the thermocouple, ensuring that the correct polarity is observed throughout. Joints in the cable should be avoided, if possible. The CJC facility must be enabled (normal conditions) for this input (see Subsection 3.4).

NOTE: Do not run thermocouple cables adjacent to power-carrying conductors. If the wiring is run in a conduit, use a separate conduit for the thermocouple wiring. If the thermocouple is grounded, this must be done at one point only. If the thermocouple extension lead is shielded, the shield must be grounded at one point only.

1.3.4RTD Inputs

The compensating lead should be connected to Terminal 4. For two-wire RTD inputs, Terminals 4 and 5 should be linked. The extension leads should be of copper and the resistance of the wires connecting the resistance element should not exceed 5 ohms per lead (the leads should be of equal resistance).
