WARNING! To avoid operator hazards and damages of
the device, the following instructions have to be worked
out by qualified technical personnel.
1.4 Limitation of liability
By non-observance of the operating manual, inappropriate
use, modification or damage, no liability is assumed and
warranty claims will be excluded.
1.5 Intended use
- The field display PA 440 is supplied by the analogue
current loop and shows the measured value on the dis-
play. For monitoring the limit values optionally up to two
PNP open collector-contacts are available. As standard
the PA 440 is equipped with a LC-display, optionally a
LED-display is deliverable.
- The configuration is menu-driven via two push buttons
located in the front. Following parameters could be con-
figured: decimal point, zero point, end point, switch-on
and switch-off points, etc. Those parameters are being
stored in an EEPROM and, thus, are being kept also in
case of power breakdown. Limit exceeding in both direc-
tions can be displayed as a message. Furthermore an
access protection is provided.
- It is the operator's responsibility to check and verify the
suitability of the device for the intended application. If
any doubts remain, please contact our sales department
in order to ensure proper usage. BD SENSORS is not
liable for any incorrect selections and their effects!
