13 MEASUREMENTS AND ADJUSTMENTS
13.1.Adjustment of the secondary interlock switch (SAFETY SWITCH B) (Right and Left side)
1.Switch operation
When the door is slightly opened, the secondary interlock switch opens the main circuit. The movement of the door from the closed position to the operation position (shown as liter) of the switch when it opens the main circuit, must maintain within following tolerances.
SECONDARY INTERLOCK SEITCH (liter) = 3 mm — 5 mm (When secondary interlock switch opens the main circuit)
NOTE:
Make sure that primary interlock switch turns off prior to the secondary interlock switch when the door is gradually opened.
2.How to adjust secondary interlock switch
Loosen 2 screws which secure the secondary interlock switch bracket to the bracket of the oven assembly and then adjust the secondary interlock switch bracket by moving it to either direction as shown in figure.
13.2.Adjustment of the Short Switch (MONITOR SWITCH) (Right and Left side)
1.When the door is slightly opened, the Short Switch opens the main circuit and closes the contacts for short circuit. The movement of door from its closed position to open position at which the Short Switch contacts open the main circuit (shown as liter) must maintain within 8 mm — 11 mm and at which the switch contacts close the short circuit should be 20mm — 35 mm.
2.How to adjust
Loosen the 2 screws holding the short switch to the short switch bracket, and then adjust the safety switch A by moving it to either direction as shown in figure.
