5.7.2 connecting of system safety interlocks
These switches are connected to the ‘dark green’ 3 pole plug. The central pole provides the common
output (230V AC). The left hand terminal enables the lower module and the right hand terminal enables
the upper module.
5.7.3 connecting remote run indication lamps
Connection points have been provided for the connection of run indication lamps (20W max). See
“Electrical Connection Details” fig 5.7a, for terminal positions.
CAUTION: These outputs must not be linked together as this will result in false lockout being
experienced by the burner control panels.
