The SAFETY SWITCH in the 530SE CONTROL BOX is equipped with a
contact allowing remote sensing of burner lockout. The electrical
connection is made at terminal 4 on the SUB-BASE. Should lockout
occur the 530SE CONTROL BOX will supply a power source of 120VAC
to the suggested connected terminal. The maximum allowable current
draw on this terminal (4) is 1 Amp.
In applications requiring CSD-1 compliance a manual safety high limit
switch must be installed Interrupting power to the burner.
