11 APPENDICES

11.1 Appendix 1

Jumper Positions - Internal to the controller

JP 1

Selects the input voltage 220 VAC.

JP 2

Selects the input voltage 110 VAC.

JP 3

Solder bridge selects between Pt100 and Pt1000.

Fuse

Note that there is a fuse (slow-blow 100mA) internal
to the controller. Before opening the unit, 

ENSURE

that the power cable is physically separated from the
power supply. Replace fuse with the recommended
type only.
