Full Gauge Controls MT-622Ri Manual

1 - DESCRIPTION
MT-622Ri is a temperature controller that uses a J type thermocouple sensor; it has two outputs for
temperature control and an internal audible alarm. It also has a timer that can operate in different modes,
triggered by digital inputs, which indicates the end time of one or two processes.
The first stage can use a cyclic preheating mode, and the second stage may operate as an alarm, cyclic
timer or indication of the end of a process. You can also use 5 configurable formulas, which allow one to
quickly change the values of the setpoint temperature and the hysteresis of the first stage and the
process time.

4 - SETTINGS
4.1 - Adjust the control temperature (SETPOINT) and process
time.
If it is configured not to use formulas (F03 = 0):
- Press and hold the @ key for two seconds, until the message [SEt] appears;
- Then the message [SP1] will appear and it will be possible to adjust the stage 1 setpoint;
- Use the keys > and < to change the value, and press @ to confirm.
It will then be possible to adjust the setpoint of stage 2 [SP2] and the process time ( [TMR] ).
Note: The adjustment of the stage 2 setpoint can only be configured if the unit is set to operate as a
thermostat (F29 = 0 or 1).
If it is set to use formulas (F03 = 1):
Each formula can be configured to use different values for the setpoint, hysteresis of stage 1 and
the time of the process. To select the formula:
- Press and hold the @ key for two seconds, until the message [SEt] and [Sp1] appears;
- You will then see the currently selected formula.
- Use the > or < keys to select which of the 5 formulas will be used:
[rc1] - Formula 1;
[rc2] - Formula 2;
[rc3] - Formula 3;
[rc4] - Formula 4;
[rc5] - Formula 5.
To confirm the selection, press @.
Then one can adjust the setpoint of stage 2 [SP2], if configured to operate as a thermostat (F29 =
0 or 1).
Note: The values of the functions of each formula are configured in the parameter menu.
4.2 - Changing Parameters
- Access the F01 function by simultaneously pressing the > and < keys for 2 seconds until [fun]
appears, then release. [F01] will then appear, press @ (short press).
- Use the > or < keys to enter the access code (123) and, when ready, press @.
- Use the > or < keys to access the desired function.
- After selecting the function, press @ (short press) to display the value configured for that function.
- Use the > or < keys to change the value, and when ready, press @ to store the configured
value and return to the function menu.
- To exit the menu and return to normal operation (temperature indication) press @ (long press) until
[---] appears.

4.4 - Description of parameters
F01 - Access Code
This is necessary when you want to change the configuration parameters. It is not necessary to insert
this code to see the set parameters.
F02 - Indicator Offset (offset)
Allows the compensation of eventual deviations in temperature reading, caused by the change of the
sensor or changing the length of the cable.
F03 - Using formulas in the 1st stage
Allows one to configure the controller in order to use the formulas or not:
[,0,] - No: If setup this way, the instrument will not use the receipt values in the control routines. For
this, setpoint 1 [SP1] will be used and process time [tmr], which are adjusted through the easy
access menu. The differential control to be used will be the same as formula 1, [F09] "Differential
control of the 1st stage (rc1)."
The value set in [sp1] can be set between [F21] "Minimum setpoint allowed to the end user (1st
stage)" and [F22] "Maximum setpoint allowed to the end user (1st stage)."
[,1,] - Yes: If configured this way, the instrument uses the control routines of the setpoint values,
differential control and process time of the formula that is active.
The formula selection will be made through the easy access menu, in the same way as adjusting the
setpoint. However, the value shown on the display will be the name of the formula that is active.
Example: [Rc1]
F04 - Operation setpoint for the 1st stage (rc1)
F05 - Operation setpoint for the 1st stage (rc2)
F06 - Operation setpoint for the 1st stage (rc3)
F07 - Operation setpoint for the 1st stage (rc4)
F08 - Operation setpoint for the 1st stage (rc5)
