Bench Test:
For incoming inspection or failure evaluation, connect the P528 to a dc voltage supply (off).
The voltage supply should be set to 5 volts.
Connect the output leads to a volt meter. With no pressure on the unit, turn on the power supply and read
the output signal on the volt meter.
The reading should correspond to the specification indicated for null offset. If not, check the connections,
wire color code and the setting of the power supply.
Electrical Installation and Wiring Guide
Safety Considerations:
Prior to installation and start-up of the P528 Pressure Sensor, you should verify that you have selected the
appropriate scale range, and that the P500 meets your desired performance and specific measurement
conditions.
You MUST observe the relevant local/national regulations and observe the applicable standards and
directives for special applications (e.g. with dangerous media such as acetylene, flammable gasses or
liquids and toxic gases or liquids and with refrigeration plants or compressors).
Should you NOT observe
the appropriate regulations, serious injuries and/or damage can occur!
Open pressure connections only after the system is without pressure!
DO NOT use the P528 outside of the overload threshold. Make sure that the device is used only within the
overload threshold limit at all times.
Observe the ambient working conditions of the P528.
Only use the P528 with compatible liquids and gases and avoid installing the sensor in an environment
with mechanical hazards.
Only use the P528 in accordance with the installation guidelines as described within this document:
