Full Gauge Controls MT-512Ri LOG Manual

1. DESCRIPTION
The MT-512Ri LOG is a temperature controller and indicator, with a joined cyclical timer. Controls
cooling and defrost through compressor shutdowns. It also has an internal datalogger and a serial
output for communication with the SITRAD . ®
Product complies with NSF (United States).
2. APPLICATIONS
• Counters
• Cooled chambers

Datalogger operation mode
This indicates how the data storage device operates:
Always OFF
Always ON
Manual operation
Offset indication
Allows it to compensate for eventual temperature misreading, usually due to a sensor replacement.
Minimum setpoint allowed to the end user
Electronic limit whose purpose is prevent that too low setpoint temperatures are regulated.
Maximum setpoint allowed to the end user
Electronic limit whose purpose is prevent that too high setpoint temperatures are regulated.
Control differential (hysteresis)
It is the difference of temperature (hysteresis) between to turn OFF and turn ON the refrigeration output.

Delay to turn the cooling output on
It is the minimum time that
the next stop.
Cooling time
It is the time which compressor will turn on and turn off only by sensor temperature . After passed this
time, the controller will enter in defrost mode.
Defrosting time
It is the minimum time that the cooling output will keep off to make natural defrost. After passed this time,
the controller will enter in cooling mode.
Initial state up on energizing the instrumen
Indicates what mode the controller will work when turned on :
Cooling
Defrost
Indication of the temperature locked during defrost
This function prevents the visualization of temperature elevation during defrost, maintaining the last
temperature indication prior to defrost. At the beginning of the refrigeration cycle, a normal temperature
indication will again take place after fan delay.
No
Yes
Delay on the activation of the instrument
When the instrument is powered on, its control is kept disabled during a time, delaying the start of process.
During this time, it works only as temperature indicator.
Additional time at the end of the first cycle
Complement time at the first refrigeration cycle to certify that the first defrost cycle do not be started very
early.
Datalogger sampling interval

Variation of the output to force data recording
Indicates whether the change in the cooling output will force the recording of data in memory regardless
of the time of sampling set in F13:
