Product Overview; Function; Storage - Helios EDR Installation And Operation Manual

Installation and Operating Specification EDR
Electrical equipment must be checked regularly: Loose connections are to be re-
•
tightened and damaged lines or cables must be replaced immediately.
Never clean electrical equipment with water or similar liquids.
•
A separate fault and performance monitoring-system with an alarm signal function is
•
necessary in order to prevent personal injuries and material damages during
malfunctions and in case the device fails. Substitute operation must be taken into
consideration!
Intended use
These devices are intended exclusively for measured value acquisition of differential
pressures (non-aggressive gases). Their operation is only permitted under observance
of the specifications in these operating instructions.
Any other use above and beyond this will be considered as improper use. The manufac-
turer will not be liable for any damage resulting from this. The company using it bears the
sole risk.

3 Product overview

3.1 Function

Sensor-control module with differential-pressure sensors in proven ceramic-cantilever
technology for climate and clean-room application.
The pressure range goes from 0...1000 Pa (0...4.0 in.wg), four measuring ranges are
programmable.
Function when the pressure at the "Plus"- connection exceeds the pressure at the
"Minus"- connection.
Depending on the programmed Mode the device can be used as sensor or as a
control module for pressure.
For operation as pressure sensor the device supplies an output signal (0...10 V)
•
proportional to the measuring range.
For operation as control module for pressure the purpose of the device is to reach
•
and maintain the target value set. To accomplish this, the measured actual value
(sensor value) is compared with the adjusted target value, and the controlled value is
deduced from this. Controlled output (0...10 V) e.g. for activating a speed controller
for fans or an EC-fan directly.

3.2 Storage

The device must be stored in its original packaging in a dry and weather-proof room.
•
Avoid exposure to extreme heat and cold.
•
Avoid over-long storage periods (we recommend a maximum of one year).
•
