5.4.5 Wiring for proximity sensor
CAUTION! The proximity sensors of the F series pump have three leads. Faulty wiring may
cause the proximity sensor to short circuit. Carry out the wiring carefully and accurately.
• Connect the leads of proximity sensor A with terminals 6, 7, and 8 respectively of the controller.
• Connect the leads of proximity sensor B with terminals 3, 4, and 5 respectively of the controller.
• Symbols A and B are arbitrary. The A and B may be interchanged. However, consistency
between sensor and air supply lines is necessary.

WARNING! A standard proximity sensor cannot be used when a flammable liquid is used.
Consult factory for details.
5.4.6 Wiring for Alarm Output 1
• Connect with terminals 13 & 14 for use of the leak detection alarm circuit.
• If the leak detection probes detect fluid in the pump air chambers, the circuit is closed. The red LED
(bellows) indicator is illuminated, power to the solenoid valve discontinued and alarm output 1 is activated.
5.4.7 Wiring for Alarm Output 2
• Connect with terminals 11 and 12 for the use of the time-up function alarm circuit.
• If the time set in the timer is exceeded due to suspended operation or reduced stroke rate of the pump,
the yellow time-up indicator (Time-Up) turns on. Simultaneously, the alarm output 2 is activated.
