RLM Mech Power Requirements
The RLM Mech 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.
RLM MECH for MECHANICAL DISPENSERS
General Installation
Read System Installation section, as well as this entire section of installation manual before
attempting to install the RLM Mech. Note System Installation Warnings in System
Installation section. Referring to Diagram: RLM Mech Connector/Jumper Layout in this
section, proceed with RLM Mech installation.
1. A junction box with a single receptacle outlet must be provided. See RLM Mech Power
Requirements listed below.
2. Securely mount the RLM Mech main box in a nonhazardous location according to the
suggested layout in the tank monitor installation instructions.
3. Set all jumpers on the RLM Mech 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 Mech to be configured for daisy-chaining together using, RS485 multi-drop
circuitry.
4. Mount pulsers on volume shaft of mechanical dispenser computer.
5. Identify unused switch in electric reset for use as a return switch on the RLM Mech.
6. Wire the pulsers and motor return (MR) switches to the RLM Mech.
7. Connect a PC to the installed RLM Mech’s communication cable.
8. Plug the wall transformer into the dedicated power outlet to apply power to the RLM
Mech system.
9. Run Tester Program supplied on the system diskette shipped with the RLM Mech, and
perform a preliminary test. Refer to Testing the RLM II Using Tester/WinTester in the
RLM II section of this manual.
10. Refer to Diagram: RLM Mech RS232 Cable Connector 5 Pinout when connecting to
tank monitor.
