3.2 Instrument Mounting
Mount the controller on a suitable vertical surface which will not get hot, using the 4 off 4mm
diameter mounting holes. The mounting hole spacing is marked on the back of the controller and
is 88mm x 148mm. The cable gland hole is 20mm diameter and should normally be at the
bottom to guard against moisture ingress. The instrument should be mounted away from direct
sources of heat.
SK2 is the thermocouple connector. The positive terminal is clearly marked.
SK1 is the mains/control connector:-
K1 is the switched Mains Live output to the heater contactor
K2 & K3 are not used (not connected) on the SPS5.1
K4 is Mains Live input
K5 is Mains Neutral input
K6 is Earth input (an Earth
must be fitted to this controller)
VR1 is the display contrast control
FS1 is the protective fuse:-
