2.4.6.1 Bulk Power Supply Current Requirements
Maximum current requirements for a bulk +12Vdc or bulk +24Vdc power supply used to
power a ControlWaveLP RTU can be determined by use of Table 2-13 or 2-14 respectively.
These tables provide detailed steady state and loop power current requirements.

2.5 OPERATIONAL DETAILS
ControlWaveLP RTUs are shipped from the factory with firmware that allows the unit to
be configured in conjunction with an IEC 61131 application program. This section provides
information as follows:
- Steps required to download the application load and place the unit into ‘Run’ mode.
- Steps required to download system firmware.
- Operation of the CPU Module’s Reset Switch
- Soft Switch Configurations and Communication Ports
