7 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 quali-
¿ ed, trained professional.
f Make sure that the technical data matches the operating criteria of the ma-
chine and/or the pneumatic system.
f Always set the compressed air supply to a level that ensures that the mini-
mum operating pressure is adhered to (see section 8 „Technical Data").
The reset valve (not available with DM1E) may only be actuated by a pulse
(electrical, manual, or pneumatic) of max. 3 seconds and with solenoids a + b
switched off..
For pneumatic resets, the reset pressure must be higher than or equal
to the operating pressure!
f Before valve assembly and before initial commissioning, always actuate
the reset valve to switch the DM valve to its normal position.
In this switching position, the DM valve is ready to run.
7.1 Conducting a function test
Test
1. Solenoid "a" actuated
De-energize DM1E! Actuate reset for DM2E!
Valve ready to run again.
2. Solenoid "b" actuated
De-energize DM1E! Actuate reset for DM2E!
Valve ready to run again.
3. Solenoids "a" and "b"
actuated within ¨t < 0.1 s
4. Solenoids "a" and "b"
actuated with ¨t > 0.1 s
5. After fault, permanent signal at
reset valve – solenoids "a" and "b"
or only "a" or only "b" actuated
De-energize DM1E! Actuate reset for DM2E!
Valve ready to run again.
If this function test provides deviating results, see section 4 „Service,
Repair, and Maintenance".
Each asynchronous movement of the piston elements > 0.1 s leads to the valve
switching off. 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,
• Insuf¿ cient electrical signals to valve solenoids; suitable voltage not availa-
ble,
• 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.
CAUTION
Result
Valve is in lockout position,
slight leakage at connection 3.
Valve is in lockout position,
slight leakage at connection 3.
Valve switches properly.
Valve switches to lockout position,
slight leakage at connection 3.
If the valve remains deactivated,
slight leakage at connection 3.

8 Technical Data

Design: Two redundant 3/2 directional main valve elements in seat-valve de-
sign, normally closed. Pneumatically operated. Combined spring and air reset.
Actuation: Solenoid-operated pilot control.
Medium: Compressed air (neutral gases), ¿ ltered in acc. with ISO 8573-1
(class 7 / 40 —m, recommended: class 6 / 5 —m), oiled or oil-free (mineral oils
according to DIN 51519/ISO-VG, viscosity class 32).
Pressure range: 2 to 8 bar. Ambient temperature: -10°C to 50°C. Medi-
um temperature: 4°C to 80°C.
For temperatures below 4°C, the compressed air must be dried according
to ISO 8573-3, class 7.
Shock test (based on DIN EN 60068-2-27):
• Acceleration: 30 g.
• Shock duration: 18 ms.
• Shock waveform: Half-sine.
• Vibration test (vibration based on DIN EN 60068-2-6):
• Frequency: 10 to 55 Hz.
• Amplitude: 0.35 mm ± 0.05 mm.
Min. switching frequency: 1x per month, to ensure proper function
Max. switching frequency: 30 Hz measured without volume. The switching
frequency decreases depending on the volume to be controlled.
Mounting orientation: Any, preferably vertical.
Monitoring: Dynamic, cyclic, internal – with any change in switching state and
in any switching state.
Solenoids: Version as per VDE 0580. Designed for continuous operation
Electrical connection according to DIN EN 175301-803 form A (previously
DIN 43650, form A). Protection class according to DIN 400 50 IP 65.
Status indicator unit optional (pressure switch): NO/NC contacts –
5 A 250 VAC, or 5 A 30 VDC.
Standard voltages: 24 V DC, 110 V 50-60 Hz, 220/230 V 50-60 Hz,
other voltages on request.
Voltage tolerance: ±10%.
