TSM-35 Screw Pocket Machine Troubleshooting
35.10 Machine will not start:
Confirm that the machine will not turn on – no motor running vs the cycle will not start
!***ALWAYS DISCONNECT POWER AND AIR WHEN CHECKING SWITCHES ***!
• Check the safety interlock switch (See 35.11)
o One of the most common reasons
o Switch is a failsafe and will not allow the machine to start if the lid is
up
o Often becomes impacted with sawdust and will not function
Open switch and blow out
• There have been several different types of switches
used over time. Get brand name of switch:
o ABB – E03300
o IDEC – E03340
o Omron – E03340 (IDEC and Omron have the same key.)
o Telemechanique – E35001
o Siemens – use E03340 and request Omron type
• Check the contacts at the back of the start and stop buttons (E03000 Stop & E35041
Start)
o See 35.12 & 35.13
o This is a continuity check – there should be a change in continuity when the buttons are
depressed. Can be done with no power to the machine.
• Check the air pressure switch (E35420
) (See 35.14)
o The air pressure switch is set at 40 psi at the factory. It can often go bad and be hard to
diagnose.
o The easiest way to check is to bridge the two wires and see if the machine will turn on.
o We no longer use the air pressure switch. Customers can keep the bridge in place if they do
not wish to replace.
