## Notes: 

A In modes 2 and 3, after the time is up and the output turns off, a reset signal is not required before another start signal is given. The start signal itself will also effect a reset first. 

Notes: 

B In mode 2, if another start signal is applied before timing is up, the elapsed time resets and starts again, without the output turning off. Further, repeated start signals within the elapsed time can prevent the output turning off indefinitely. Therefore, the TDMS can be used in conjunction with IMO sensors to detect that machine shafts have stopped rotating before maintenance is carried out. Contact IMO for details.
