RLM II Power Requirements
The RLM II must be powered from a dedicated 115 VAC single circuit breaker, with no other devices
connected to wire or breaker. Do not use a switched neutral breaker. The neutral must come directly from
the neutral bus in the electric supply panel. No other neutral circuits may be connected to this wire.
The electric supply system earth bond must connect to a driven ground rod or other earth bonding systems
that comply with the National Electrical Code, Article 250.
Failure to comply with these requirements will void warranty.
RLM II for ELECTRONIC DISPENSERS
General Installation
Read previous sections, as well as this entire section of installation manual before
attempting to install the RLM II. Note System Installation Warnings in previous section.
1. A junction box with a single receptacle outlet must be provided. (See RLM II Power
Requirements listed below.)
2. Securely mount the RLM II main box in a nonhazardous location according to the
suggested layout in the Tank Monitor Installation instructions.
3. Referring to Diagram: RLM II Main Board Jumper Selections on the next page, set all
jumpers on the RLM II main board according to the specific application requirements.
These settings affect the tank monitor communications parameters such as baud rate,
parity, data bits and device addressing. Also, these jumpers allow the RLM II to be
configured for daisy-chaining together using RS485 multi-drop circuitry.
4. Connect a PC to the installed RLM II.
5. Plug the wall transformer into the dedicated power outlet to apply power to the RLM II
system.
6. Run Tester or WinTester program to perform a preliminary test. These programs are
available on our website: www.pie-corp.com.
