Electrical Connections
•
Depending on the voltage, electrical components must be provided
with a ground/earth connection and satisfy local regulations and
standards.
3-wire flying leads coil (NEMA 4, 4X)
- 2 red wires for power, 1 yellow/green wire for ground/
earth
• DIN type coil (IP65)
- 3 prong DIN 43650 Connector Form B Type I
Before work, switch off the electrical power supply to de-energize
all components.
The Bray Series 63 solenoid valve is designed for continuous duty
service. To avoid any possibility of damage or injury, do not touch the
solenoid which can become hot under normal operating conditions.
If the solenoid valve is easily accessible, the installer must provide
protection against accidental contact.
Maintenance
•
WARNING
Prior to any maintenance work or returning to operation, shut off
supply to the pilot solenoid valve, depressurize and vent the valve
in order to prevent injury or damage.
Cleaning:
Maintenance of the valve depends on the operating
conditions. They must be cleaned at regular intervals. During
servicing, the components must be checked for excessive wear.
If operation cycle is slow, ensure proper supply pressure and that
there is no unusual noise or leak detected.
• Sound Emission:
The sound emission depends on the application,
supply medium and nature of the equipment used. Exact
determination of the sound level can only be carried out by the
user having the valve installed in their system.
• Preventive Maintenance:
Operate the pilot solenoid valve
monthly to check function. Should any difficulties or questions
arise during installation and maintenance, please contact a Bray
representative.
Troubleshooting:
• Incorrect exhaust pressure:
- Check that the air supply is within the minimum (22 psi,
1.5 bar) and maximum (130 psi, 9 bar) operating pressure.
- Use a filter regulator if the air supply is not consistent.
• Pilot valve does not operate:
- Check that the manual override is disengaged.
- Ensure that the air supply meets the minimum pressure.
Tools Required
• Phillips cross drive (#2) screwdriver, to assemble the solenoid coil
