Operation; Care And Maintenance - Aventics IS12-PD Betriebsanleitung

AVENTICS | IS12-PD | R422003649–BAL–001–AB | English
Malfunction due to damaged sensor cable!
If the seal in the sensor plug is missing or defective, protection class IP65 is not
achieved.
O Make sure that the seals are integrated in the plug and not damaged.
Damage to the sensor due to excessive voltage!
The ST4 sensor may only be operated with 10–30 V DC even if you use 110 V AC or
230 V AC coils.
O Make sure that the ST4 sensor is always operated within the voltage limits.
O Connect the sensor plug and the knurled nuts to the controller. See the table for
the pin assignment (above).
We recommend using short circuit protection.
Assembling the coil
Use of improper coils!
Using improper coils can result in malfunctions.
O Only used the coils named under "Intended use".
You can assemble the coil in 5 different positions so that the contacts face upward,
45°, or 90° to the side.
1. Assemble the coil on the pole tube.
The small centerings must be fixed in the steel plate so that the coil is prevented
from turning.
2. Tighten the lock nuts ( –9) on the thread at the end of the pole tube.

Tightening torque: 0.6 +0.2 Nm.
Connecting the coil
To connect the coil, you need cables with the following connections:
W
one electrical connector according to ISO 4400, form A, CN1 series,
W
or one M12x1 socket, 3-pin, A-coded.
The cable and connectors are not part of the scope of delivery. The pin assignments
for the connection cables are displayed in Fig.
O Connect the electrical connector or the M12 socket to the coil. Make sure that the
seals have been inserted correctly. Tighten the screw on the coil (form A) or the
knurled nuts to the M12 plug.
Screw tightening torque: 0.4 +0.1 Nm
8 Commissioning
Danger of injury while working on the system!
Working while the system is running can cause major injuries from moving
machinery.
O Maintain a sufficient safety distance to moving machine components.
O Do not work on the system while it is running.
Risk of injury when actuating the manual override!
Uncontrolled movement of the system components!
O Before actuating the manual override, make sure that it will not trigger
uncontrolled system movements.
Checking the connections
O Before commissioning, make sure that all plugs are correctly connected to
ensure protection class IP65.
Initial check of the spool position detection
For valves with manual override (MO), you can simplify commissioning by actuating
the MO. The MO on the IS12-PD valves is "without detent". This means that the valve
switches to home position when you discontinue actuating the MO.
O Before initial operation, check whether the "spool position detection" function is
working properly.
– If the valve is not actuated (electrically or mechanically on the MO), the sensor
LED should be lit. The output voltage is applied to pin 4 (OUT).
– If the valve is actuated (electrically or mechanically on the MO), the sensor LED
must not be lit. 0 volts are applied to pin 4 (OUT).

Operation

Loss of function if the minimum control pressure is not met!
If the control pressure falls below 3 bar, the valve can no longer switch reliably.
The safety function is then affected.
O Make sure that the minimum control pressure is always above 3 bar.
O For valves with internal pilot, ensure the operating pressure with an
appropriate pressure sensor, or the control pressure for valves with external
pilot respectively.
Spool position detection malfunction due to magnetic sources!
Spool position detection may malfunction due to magnetic sources. The safety
function is then affected.
O Make sure that no magnetic sources are located near the valve.
O Make sure that the operating conditions correspond to the catalog specifications
for size 2 IS12-PD valves, for CO1 coils, and for ST4 sensors, particularly with
regard to temperature, pressure, voltage supply, and mechanical and climatic
loads (see also chapter "15 Technical Data").
O Use compressed air with the following properties:
W
Maximum particle size 5 μm
W
Oil-free compressed air: 0 mg/m
W
The pressure dew point must be at least 15°C below the ambient temperature
and must not exceed 3°C.
W
Safe isolation according to DIN EN 60742, classification VDE 0551

10 Care and Maintenance

Cleaning
Damage to the product due to the use of aggressive cleaning agents!
The product can be damaged if washed with a cleaning agent. The chemical
resistance of the valve material to such products is not guaranteed.
O Make sure that no cleaning agents come into contact with the valve.
Damage to the product due to washing at high pressures and temperatures!
The product will be damaged if you clean it with high pressure and/or at a high
temperature.
O Make sure that the product is not cleaned with high pressure and/or at a high
temperature.
Maintenance
Risk of injury while working on a running system!
Working while the system is running can cause major injuries from moving
machinery.
O Bring the system mode into a state in which working movements are no longer
possible. Wait until all moving machine parts come to a standstill, and protect
the system against being switched on.
Danger of personal injury due to uncontrolled movements!
For valves with manual override (MO), you can simplify system maintenance by
mechanically actuating the MO. The MO on the IS12-PD valves is "without detent".
This means that the valve switches to home position when you discontinue
actuating the MO.
O Make sure that no uncontrolled movements occur in the process.
IS12-PD valves are maintenance-free. However, the seals of the valves may age
faster under aggressive ambient conditions. Defective seals will lead to pneumatics
leaks and non-compliance with the IP65 protection class.
O Check regularly whether all plug connectors are firmly fitted.
O Establish the maintenance intervals according to your ambient conditions and
enter them in the system-dependent maintenance plan.
O Observe the system-specific maintenance intervals.
The operator is responsible for determining the maintenance intervals.
