1.3.1 Mains (Line) Input

The Controller will operate on 96 - 264V AC 50/60Hz mains (line) supply. The power

consumption is approximately 4 VA.

CAUTION:

This equipment is designed for installation in an enclosure which

provides adequate protection against electric shock. Local regulations

regarding electrical installation should be rigidly observed. Consideration

should be given to prevention of access to the power terminations by

unauthorised personnel. Power should be connected via a two-pole

isolating switch (preferably situated near the equipment) and a 1A fuse, as

If the 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 Controller mains (line) supply.

1.3.2 24V (Nominal) AC/DC Supply

The supply connections for the 24V AC/DC option of the Controller are as shown in

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

1.3.3 Thermocouple Input

The correct type of thermocouple extension leadwire or compensating cable

must be used for the entire distance between the Controller and the

thermocouple, ensuring that the correct polarity is observed throughout. Joints in

the cable should be avoided, if possible. The Controller’s CJC facility must be

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.
