Recycling and disposal
Most valve controller parts can be recycled if sorted accord-
ing to material.
Most parts have material marking. A material list is supplied
with the valve controller. In addition, separate recycling and
disposal instructions are available from the manufacturer.
A valve controller may also be returned to the manufacturer
for recycling and disposal. There will be a charge for this.

Safety precautions

TRANSPORTATION, RECEPTION AND
STORAGE
The on/off controller is a sophisticated instrument, handle it
with care.
Check the controller for any damage that may have
occurred during transportation.
Store the controller preferably indoors, keep it away
from rain and dust.
Do not unpack the device until installing it.
Do not drop or knock the controller.
Keep the flow ports and cable glands plugged until
installing.
Follow instructions elsewhere in this manual.
CAUTION:
Do not exceed the permitted values!
Exceeding the permitted values marked on the valve con-
troller may cause damage to the controller and to equip-
ment attached to the controller and could lead to
uncontrolled pressure release in the worst case. Damage
to the equipment and personal injury may result.
CAUTION:
Cover should be opened only in dry places, not when
the device is vulnerable to e.g. salt water.
CAUTION:
Do not remove or dismantle a pressurized controller!
Removing or dismantling a pressurized prestage or spool
valve of an SwitchGuard leads to uncontrolled pressure
release. Always shut off the supply air and release the
pressure from the pipelines and equipment before remov-
ing or dismantling the controller. Otherwise personal
injury and damage to equipment may result.
WARNING:
During calibration and tuning the valve operates
between open and closed positions. Make sure that
the operation does not endanger people or processes!
WARNING:
Do not operate the device with the cover removed!
Electromagnetic immunity is reduced, valve may stroke.
Ex WARNING:
The locking screw (part 107) of the cover is essential
to explosion protection.
The cover has to be locked in place for Ex d protection.
The screw grounds the cover to the housing.
Ex WARNING:
Spark hazard!
Protect the aluminium housing and cover from impacts.
Ex WARNING:
Electrostatic charge hazard!
The pointer and display windows are non-conductive.
Clean with a damp cloth only!
Ex WARNING:
Electrostatic charge hazard!
The paint of the device can enable charging of the metal
parts by high voltage sources. Do not install the device in
proximity of high voltage sources!
Ex i WARNING:
Ensure that the complete installation and wiring is
intrinsically safe before operating the device!
Ex i WARNING:
Do not operate the device with electronics cover (39)
removed!
Electromagnetic immunity is reduced, valve may stroke.
Ex i: intrinsic safety may be impaired.
Ex i WARNING:
For intrinsically safe applications, the equipment must
be connected via a certified Zener barrier placed out-
side the hazardous area!
Ex d NOTE:
Only persons familiar with Ex d explosion protection are
allowed to work with the device. Special attention has to
be paid to careful handling and closing of the cover.
Ex d WARNING:
Do not open the cover when an explosive atmosphere
may be present!
Ex d WARNING:
Use a cable gland with suitable Ex d certification.
For ambient temperature over 70 °C / 158 °F use a heat
resistant cable and cable gland suitable for at least
90 °C / 194 °F.
ELECTRICAL SAFETY WARNING:
Use fuses for limit switch installations with
50 V AC / 75 V DC or higher.
NOTE:
Avoid earthing a welding machine in close proximity to an
SG9000H valve controller.
Damage to the equipment may result.
