TM50 Temperature Controller Settings

TM50 Temperature Controller Settings

Omron E5GN Temperature Controller

The Omron E5GN Temperature Controller is used to monitor and maintain a target temperature range for the sealing shoes of the heat sealer. The heat sealer is equipped with two controllers, which control the two sealer shoes (inside and outside) independently. The controllers are set by default to maintain a temperature range equal to the set point +/-10 degrees for their respective sealer shoe. The controller does this by comparing the present value (current temperature) to the set point (target temperature). It turns on the heating element in the sealer shoe whenever the present value drops to 10 degrees below the set point and allows them to cool when the present value rises to 10 degrees above the target temperature.

Adjusting the Set Points

To adjust the set point, simply press the increment or decrement keys (up and down arrows). The green Set Point Display will show the changes and the controller will immediately begin adjusting the temperature of the sealer shoes according to the new range that results. If a large adjustment is required, pressing and holding the up or down arrow keys will increase or decrease the set point quickly.

Initial Settings (Figure 1.4)

TM50-Fig1 4

  1. Press the Level Key for at least three seconds. The PV display will flash after one second and temperature control will stop. The controller is then in Initial Settings Level.
  2. The Input Type parameter will display as In-T. It should be set to 2. This setting corresponds to the J type thermocouple used in V-TEK sealers.
  3. Select the Temperature Unit parameter, displayed as d-u, by pressing the Mode Key. It should set to C, which selects Celsius.
  4. Select the Control Period parameter, displayed as CP, by pressing the Mode Key.
    It should be set to 5.
  5. Select the Direct/Reverse Operation parameter, displayed as orEu. It Should be set to or-r.
  6. Select the PID/On-Off parameter, displayed as CntL. It should be set to Pid.
