Remote Monitoring and Control Unit
Technical Reference Manual
REC 523
4.2.
Requirements
If the environmental conditions differ from those specified in Chapter 7. Technical
data, as to temperature and humidity, or if the atmosphere around the unit contains
chemically active gases or dust, the device should be visually inspected in
connection with the REC 523 secondary testing. The visual inspection should focus
on:
• Signs of mechanical damage to device case and terminals.
• Dust inside the device cover or case; remove carefully with compressed air.
• Signs of corrosion on terminals, case or inside the device.
For information about the maintenance of REC 523, refer to Chapter 8. Service.
4.3.
Configuration
The REC 523 units are adapted to specific applications by using the Relay
Configuration Tool included in CAP 505. The tool is used for configuring the basic
terminal, protection and logic function blocks, control and measurement functions,
timers and other functional elements included in the logic functions library. Refer to
Section 5.8.1. REC 523 configuration.
The configuration of LON network is described in Section 5.8.2. LON network
configuration. If LON communication is used without LON inputs and outputs
(network variables), the section about LON network configuration is unnecessary.
The configuration procedure starts by configuring the functions of protection
control, condition monitoring, measurement and logics with the Relay
Configuration Tool.
For more detailed information about the configuration, refer to the tool-specific
manuals (refer to Section 1.8. Related documents).
For the configuration of the remote communication protocols, refer to protocol
descriptions (refer to Section 1.8. Related documents).
If any ust inside the device cover or case is found, remove it
carefully with compressed air.
Remote control units are measuring instruments and should be
handled with care and protected against moisture and mechanical
stress, especially during transport.
