MECHANICAL INSTALLATION

The Controller is designed to be sleeve mounted in a 1/16 DIN panel cutout with only the front
panel rated to IP66, provided that:
the panel is smooth and the panel cutout is accurate;
the mounting instructions are carefully followed.

DIN PANEL CUTOUT

1/16 DIN: 45.0mm +0.6 / -0.0 wide, 45.0mm +0.6 / -0.0 high
Maximum panel thickness 9.5mm
Minimum spacing 20mm vertical, 10mm horizontal

MOUNTING

To mount a Controller proceed as follows:
1 Check that the controller is correctly orientated and then slide the unit into the cutout.
2 Slide the panel clamp over the controller sleeve pressing it firmly against the panel until
the controller is held firmly .
3 The controller front bezel and circuit board assembly can be unplugged from the sleeve.
Grasp the bezel firmly by the recesses on each side and pull. A screwdriver can be used
as a lever if required.
4 When refitting the bezel assembly it is important to press it firmly into the sleeve until the
latch clicks in order to compress the gasket and seal to IP66.

CLEANING

Wipe down with damp cloth (water only)
CAUTION: The controller should be isolated before removing or refitting it
in it's sleeve. Live circuits can hold a charge for short periods after isolation
from voltage supply. Electrostatic precautions should be observed when
handling the controller outside it's sleeve.

OUTPUT DEVICES
WARNING:
Three types of output device may be factory fitted to the controllers, and users must choose
how to allocate these to outputs SP1 and SP2. (SP3 is always RL Y). Check the model number
and output configuration against the Output Options Table on page 8 before wiring the
instrument and applying power .
1 Solid state relay drive (SSd1/SSd2)
6Vdc (nominal) 20mA max.
T o switch remote SSR (or logic)
2 Miniature power relay (rLY/rLY1/rLY3)
2A/250V AC resistive, Form A/SPST contacts.
3 Analogue Output ( AnLG ) (isolated)
Specify; 4–20mA 500 Ω max +/- 0.1% fs typical
0–5Vdc 10mA (500 Ω min) +/- 0.1% fs typical
0–10Vdc 10mA (1KΩ min) +/- 0.1% fs typical
SUPPLY VOLTAGE
100–240V 50–60HZ 6.0VA (nominal)
+/- 10% maximum permitted fluctuation
WIRING THE CONNECTOR
Use copper conductors (except on T/C input). Cable rating 80°C min. Maximum
recommended wire size: 32/0.2mm 1.0mm2 (18A WG). Prepare the cable carefully, remove a
maximum of 8mm insulation and ideally tin to avoid bridging. Prevent excessive cable strain.
INDUCTIVE LOADS
T o prolong relay contact life and suppress interference it is recommended engineering practice
to fit a snubber (0.1uf/100 ohms) between relay output terminals.
CAUTION:
Snubber leakage current can cause some electro-mechanical devices to be held ON.
Check with the manufacturers specifications.
