INSTALLATION
INSTALLATION

INSTALLATION
1. Peel adhesive back off dial and fit over 10mm panel hole.
2. See the table below for heatsink requirements & expected ambient temperature, to calculate the
maximum current rating.
3. Check that the voltage rating & sensor type is correct.
4. Insert unit through 10mm panel hole, dial and extra heatsink as appropriate, ensuring
equipotential bonding (Earth bonding) and tighten front nut. Use a ‘thin smear’ of heatsink
paste for good thermal coupling.
5. Before fitting knob, turn temperature control fully anti-clockwise to the mechanical stop.
6. Fit and align knob to coincide with the dial mark below 0ºC
7. Make wire connections to rear terminals. To monitor supply and load conditions fit neon’s
across the relevant terminals.

OPERATION
8. Note that unit will not operate or indicate correctly with loads of less than 200W, to ensure triac
latches on.
9. Set Prop. Band (via rear panel) fully anti-clockwise
10. Switch and turn dial to required temperature and allow system to heat up to a steady state. If
temperature is unstable turn Prop. Band clockwise in small steps over several minutes until
stable conditions are obtained, characterised by a steady output On/Off ratio
11. If output remains off, check for open or short circuit in sensor circuit, and if output stays on,
check position of sensor relative to heated zone. Correct sensor resistance is 10.7K @ 0ºC, 10K
@ 25ºC, 7.9K @ 100ºC.
12. Do not use Megger or other high voltage equipment as the voltage rating may be exceeded and
damage the internal components.
FUSING
It is recommended to use semiconductor fast acting type fuses and circuit breakers (Semiconductor-
MCB) for unit protection. (See SRA Datasheet for further information).
CE MARKING
This product family carries a “CE marking” . For information see recommendation section and
contact our sales desk.
INTRODUCTION
