Ordering Guide
ATG model, software and hardware options can be listed separately or combined when ordering. Systems shipped from the factory will list the combined part number. Complete part numbers have a specific order and are created using the following guidelines:
TX DPMIE / TRLGSC
- TX = Base Model Options
- T550E = EVO™ 550 base ATG
- T5000E = EVO™ 5000 base ATG
- DPMIE = Hardware Options (choose all that apply)*
- D = Display
- P = Printer
- M = Internal modem
- I = Dispenser interface module
- E = LON module
- TRLGSC = Software Options (choose all that apply)
- T = SCALD 24-hour tank testing
- R = Reconciliation/Autocalibration
- L = Line leak detection
- G = Line leak detection for generator applications**
- S = Secondary containment monitoring
- C = Recirculation, scheduling, and timer conditions
*Only one EVO-DIM or EVO-LON module can be installed per ATG.
**For use only with generator applications, always follow regulatory requirements.
Example: T550EDPMI/TRLS = EVO™ 550 base model with display, with printer, with internal modem, with dispenser interface module, with SCALD, with reconciliation/autocalibration, with line leak detection, and with secondary containment monitoring.
