CHAPTER 4 - INSTALLATION INSTRUCTIONS
The alarm relays may be configured for either normally de-energised or
normally energised operation. Check the configuration sheet supplied
with the system to determine the operating mode of the relays on
each channel. The energisation mode of the relays can be reconfigured
easily using a computer attached to the Engineering Port. Contact
Zellweger Analytics or your local agent for more information.
14.2 Analogue Output
Connecting the analogue output to a loop voltage in excess of
40V may cause permanent damage to the analogue output
module.
The Analogue Output Module provides an isolated current loop output
that follows the sensor signal level. The output circuit is a passive
current control element that can be operated with loop voltages up to
40V. The recommended connections are shown below:
