M35 Series Operating Instructions

7.1. Mechanical Installation

If attaching to an installed ROSS MD3
connection clamps. If installing as a stand-alone unit, use either (2) ROSS connection
clamp and bracket sets or install fittings directly into the inlet and outlet ports.
Visit www.rosscontrols.com for more information.
7.2. Pneumatic Installation
Connect the compressed air supply to port 1. Connect port 2 to the downstream
portion of the circuit.
7.3. Pneumatic and Electrical Connections
Electrical connections to the solenoids and sensors are made with male 5-pin M12
receptacles on the valve. See Pinouts on page 2. Female connectors and cables are
sold separately. The cables and cable connections as well as the electrical control for
the double valves must comply with the applicable safety regulations.

8. Commissioning and Operation

Damage to health due to loud noise!
Levels above 70 dB(A) may lead to damage to health!
f Always wear ear protectors when working on the product.
Before commissioning, the installation has to be carefully inspected by a qualified,
trained professional.
Make sure that the technical specifications matches the operating criteria of the
machine and/or the pneumatic system.
Always set the compressed air supply to a level that ensures that the minimum
operating pressure is adhered to (see section 10 Technical Specifications).

8.1. Test Procedure

1. Only Solenoid A energized – Valve is faulted, supply is shut off, downstream air
exhausts through port 3. Sensor A is off, sensor B is on.
2. Reset valve by de-energizing both solenoids – Valve is off, supply is shut off, and
downstream air is exhausted through port 3. Sensors A & B are on.
3. Only Solenoid B energized – Valve is faulted, supply is shut off, downstream air
exhausts through port 3. Sensor A is on, sensor B is off.
4. Reset valve by de-energizing both solenoids – Valve is off, supply is shut off, and
downstream air is exhausted through port 3. Sensors A & B are on.
5. Solenoids A & B energized
Valve is on, air pressure is supplied downstream through port 2 and port 3 is shut
off. Sensors A & B are off.
6. Solenoids A & B de-energized – Valve is off, supply is shut off, and downstream
air is exhausted through port 3. Sensors A & B are on.
NOTE: Test 1 & 3 can only be conducted for solenoid configuration "A" (M35***AEXA**A).
Results from the test procedure other than those listed above could indicate a valve
malfunction. See section 5, Service, Repair, and Maintenance.
Failure of the valve to shift synchronously leads to a fault in the M35 Series valve.
This could happen for a variety of reasons, such as:
• Defective piston seals
• Main valve elements experiencing a switching delay due to dirt or resinous oil
• Insufficient electrical signals to valve solenoids; suitable voltage not available
• Receipt of signals at solenoids not synchronous
• Pilot valves experiencing a switching delay due to damaged components, dirt, or
resinous oil
• Excessive water build-up in the valve.
9. Disconnecting and Removal
Risk of injury due to installation while pressurized or with live parts!
Installation while pressurized or with electrical power switched on can result in injuries due to
sudden pressure build-up or electric shock.
f De-energize and de-pressurize the relevant system parts before installing the valves.
f Secure the system to prevent it being switched back on again.
Risk of injury due to disconnecting pressurized or live parts.
• Disconnecting a pneumatic component while the system is pressurized or while
electrical power is supplied can result in injury or death due to sudden pressure
release, unexpected movement, or electric shock.
• Isolate and lock out the electrical and pneumatic systems before disconnecting the
valves.
