DESCRIPTION
The PROTUES® Mini-MeTM is a remote color-graphic display allowing Automa c Tank Gauge (ATG) users the ability to gain access to current tank and alarm informa on. ATG's monitor storage tanks for level, temperature, volume, and alarm status. They are usually installed in loca ons where the ATG's display, and audiovisual alarms are not conveniently accessible. In addi on, these tank gauges are o en difficult to use and understand. The PROTEUS Mini-Me works with all industry-standard ATG's, allowing the user to gain remote access easily and intui vely to the ATG's data and alarm status from anywhere in the world with internet connec vity. The Mini-Me features standard RS-232, RS-485, and Ethernet communica on. The Mini-Me can also be configured for wireless communica on using op onal accessories. Contact sales for details.
SAFETY
 Do not perform any installation or service procedures if you are not familiar with the National Electrical Code® and all other federal, state, and local codes and regulations pertaining to this installation.
 Do not perform any installation or service procedures until you have read and understood this entire manual.  Do not install the controller in a hazardous location.  Do not drill through the enclosure.  Do not mount where temperatures are outside of the operating temperature range (see Specifications; page
5) without a heater and/or thermostat. Contact OMNTEC sales for details and options.  Always turn off power to the controller before servicing.  Take all safety precautions to avoid accidents.
 Keep the entire work area clean.

WARNING

INSTALLATION
IMPORTANT: Read all instructions prior to starting the installation process. Do not apply power to the Mini-Me until the unit has been mounted and all wiring connections have been made. All work must be performed by authorized installers in accordance with local and National Electric Code.
120/240 VAC power wires must be combined in a separate (isolated) conduit.
Use and select the proper conduit types and sizes in accordance with applicable codes. Even in situations where they are not required by code, it is recommended that conduit is used to protect wiring.
Note: Make certain that all conduits and junction boxes are dry and watertight. Wet wires can result in the faulty operation of the system. All wires should enter the controller via proper conduit.
Reference pages 5 and 6 in this document for (lettered callout) components detailed below. Reference pages 5 and 6 in the document for (lettered callout) components detailed below.
1. Measure base mounting dimensions and fasten the supplied wall anchors. Install screws for the top two mounting flange holes (B) leaving a minimum of ¼-inch of thread exposed.
2. Mount the base onto the top two flange screws (B) then tighten and secure. 3. Fasten the two bottom flange screws (B) to the base mounting holes and secure. 4. Bring power wires (100-240 VAC) through the right-side preformed knockout (F) and secure on the power supply
(K) and grounding block (L) as illustrated.

Communication wiring and setup is either RS-232, RS485, or Ethernet depending on your preference of communication. The setup of these communication options follows below; RS-485 has two available setup options.

RS-232 SETUP

1. Bring a low-voltage RS-232 (1.5 pair or 4-conductor 22 AWG twisted pair with shield) through one of the additional preformed knockouts (E) and secure to the RS-232 connector (P).
2. Prepare the proper ATG connection for RS-232. 3. Configure the RS-232 port from the main ATG through the programming settings. 4. Power up the Mini-Me and view the programming guide to adjust system settings.

When using an RS-232 connection, the Mini-Me can connect to any industry-standard ATG.
