Sensor Adjustment..................19 Troubleshooting Guide................. 20 We would like to thank you for purchasing the TMG-1200 non-contact monitor. This guide consists of four parts: Introduction, Basic Operation, Applied Operation and Maintenance. Prior to operation, please read the TMG-1200 guide thoroughly. -
Page 3: Introduction
The multi mode is a multi-slide or progressive header (Two sensors are necessary only in the case of using the multi mode.) The TMG-1200 can be setup for operation in any of these modes. Refer to the contents of Section “System Setting”. -

(mean value ) display. 2. Set point display - Displays the monitoring range between the upper and lower limits. When the display shows a deviation exceeding the limit values, the TMG-1200 displays a fault condition. 3. Bar display – Displays the deviation from the set point. The left side of the bar display is the “-“... - Page 5 Used to change the set point or to change settings in the system mode. 19. Contrast control Used to adjust the contrast of the Liquid Crystal Display (LCD) screen. The contrast control is factory adjusted. Readjust it when the screen is difficult to see.

The procedures are described below. 1. At setup for material supply, etc., press the Reset button to cause the TMG-1200 to go to the by-pass state. Push the reset button again cancels the bypass state. -

Set table range: Absolute Value: 0 to 500 µm (in units of 10 µm.) Mean Value: 0 to 99 µm (in units of 1 µm.) • Setting the absolute value to "0" turns off absolute value detection. Page 7 TMG-1200 Instruction Manual... -

• Slowdown detection The TMG-1200 has a slowdown detection function. When the rpm of the machine has decreased due to machine trouble, this function stops the machine. The rpm when the machine was started in the continuous mode is kept in memory. When the rpm becomes lower than that at the start by more than the set value, a fault signal is produced and the screen display shows that the machine has stopped due to slowdown. -
Page 15: Details Of System Setting
Details of System Setting The operation of the TMG-1200 can be varied by system setting to enable the device to be used in various ways. Being preset, system settings items do not need to be changed. How to change them is described below. - Page 16 Set the output time (one shot) of the counter output relay which provides an output signal when the preset counter value agrees with the preset set point. The set table time is 0.5-25 seconds in units of 0.1 second. Initial value: 1 second Page 15 TMG-1200 Instruction Manual...
