SMX 100 Refrigeration Controller, Data Logger and Alarm
 
SOLAR MULTI

The SMX 100 is a microprocessor-based refrigeration controller. It uses modern thermo technologies and three fully sealed plug-in PT100 platinum film temperature sensors to ensure that the cold-room is controlled and monitored with the greatest of ease.
The large graphics LCD display and touch sensitive dials offer a user friendly  man machine interface. Programming and setting of temperatures and defrost cycles are very friendly and uncomplicated. It offers 12 adjustable defrost cycles. One sample of product temperature is logged every 15 minutes and stored on an internal memory.
This novel approach of a paperless logging and filing system allows the data of any day in its history to be read and examined with just a few key presses.

  • Status screen for indication of system state
  • Diagnostics screen for trouble-shooting
  • Alarm history record for low alarm, high alarm and power fail
  • Battery back-up for power blackout operation

 

Data Logger

  • Paperless data logger with automatic filing by date
  • Product temperature sampled and stored every 15 minutes
  • Defrost and alarm state sampled and stored every 15 minutes
  • Contents of internal databank can be transferred directly to the PC using the MASTERLINK Software or via a MASTERLINK Hardware module.
  • "Percentage of internal databank used" indication in bar graph and digital form
  • "Internal databank almost full" indication with 3 weeks notice before data transfer is necessary.
  • 2.5 Year internal reusable databank for datalogging

 

Three identical temperature sensors are included in a standard package. Each sensor is supplied with 45 feet of outdoor cable. If required, sensor extenders are available. If sensors need to be extended and factory-made extenders are not available, they can be extended using a suitable four core cable.
