Optionally co-design standards:
1 .I This European standard establishes the requirements and tests applied to safety switching devices for lirniting
the pressure - here after called devices - to ensure that the maximum or minimum pressure, which is caused by a
pressure generator in refrigerating systems andfor heat pumps, is rnaintained within the limits of the refrigerating
system andlor heat pump. These devices are of special construction equipped with mechanically operated output
contacts.
NOTE: Devices may be wired directly into the control circuit of the compressor or may be connected through ,
a relay or microprocessor/computer.
Transducers/analogue devices are not covered by this standard.
If more stringent specifications for special applications are necessary, these should be agreed between the customer
and the manufacturer of the devices.
1.2 Different safety and control functions can be combined in one device.
1.3 This standard does not apply to devices used for control purposes.
