6. ACCEPTANCE TESTS
FUNCTION F:
89 OPEN:
• Apply auxiliary voltage only to PI2 (89 open)
• Apply Vac voltage corresponding to half the voltage presence setting to V1.
• Increase V1 and check that terminal SP9 is activated for 100% and deactivated for 96% of the voltage
presence setting.
89 CLOSED, VOLTAGE IN PHASE A:
• Apply auxiliary voltage only to PI1(89 closed)
• Apply Vac voltage corresponding to half the voltage presence setting to V3.
• Increase V3 and check that terminal SP9 is activated for 100% and deactivated for 96% of the voltage
presence setting.
VOLTAGE IN PHASE B:
• Apply Vac voltage corresponding to half the voltage presence setting to V4.
• Increase V4 and check that terminal SP9 is activated for 100% and deactivated for 96% of the voltage
presence setting.
VOLTAGE IN PHASE C:
• Apply Vac voltage corresponding to half the voltage presence setting to V5.
• Increase V5 and check that terminal SP9 is activated for 100% and deactivated for 96% of the voltage
presence setting.
FUNCTION J:
89 UNDETERMINED:
• Apply auxiliary voltage to PI1 and PI2 (89 undetermined)
• Apply Vac voltage corresponding to half the voltage presence setting to V1.
• Increase V1 and check that terminal SP21 is activated for 100% and deactivated for 96% of the voltage
presence setting.
89 OPEN:
• Apply auxiliary voltage only to PI2 (89 open)
• Apply Vac voltage corresponding to half the voltage presence setting to V2.

presence setting.
89 CLOSED, VOLTAGE IN PHASE A:
• Apply auxiliary voltage only to PI1 (89 closed)
• Apply Vac voltage corresponding to half the voltage presence setting to V3.
• Increase V3 and check that terminal SP21 is activated for 100% and deactivated for 96% of the voltage
presence setting.
VOLTAGE IN PHASE B:
