SCHEMATIC OF VALVE
TROUBLESHOOTING:
1) Attach a voltmeter to terminals 1 and 2. Power (24 volts) should always be present on 1 and 2. If power is interrupted check
transformer or power source.
2) With a voltmeter attached as above, jumper terminals 5 and 4 to verify the valve opens. If power is present on 1 and 2 but
the valve fails to open check connections. Replace motor assembly (replacement Motor # F19-0097) if condition persists.
When the valve opens, break the connection between 5 and 4 and jumper between 5 and 6. The valve should close. If the
valve fails to close replace motor assembly.
3) Terminals 2 and 3 (auxiliary circuit) become the same point electrically when the valve opens. Because terminal 2 is 24 volts
hot, a voltmeter should read 24 volts between terminal 3 and terminal 1 (neutral) when the valve is open.
Note: If the auxiliary circuit terminals (2 and 3) are being attached to a control circuit with a separate transformer the trans-
formers must be in phase or one transformer may be damaged. If phasing the transformers is not possible a 24 volt isolation
relay can be installed with the coil attached to terminals 1 and 3 and the contacts can be used to operate the control circuit.
The relay will energize when the valve opens.
