How to fix a Donaldson Torit STi ODC-TC Timer that does not turn on?
- M
  Mitchell JamesAug 15, 2025
  If your Donaldson Torit Timer isn't turning on, start by checking the power supply to ensure it's active and at the correct voltage. Then, verify the cable connection at terminal J4 (for AC power) or terminal J7 (for DC power) is secure. If the issue persists, the timer master card may be damaged and need replacement. When requesting a replacement, provide the timer's serial number and the details from the QC sticker to speed up the process.

Why are the pulses weak on my Donaldson Torit Timer?

  Michaela SullivanAug 20, 2025
  Weak pulses in your Donaldson Torit Timer could stem from a few causes. First, check the voltage supplied to the timer, as a low voltage may not fully open the valves. Next, inspect the pneumatic tubing between the solenoid and diaphragm valves, ensuring both ends are securely attached to the valve fittings. Finally, verify that the compressed air being delivered to the diaphragm valves is at the recommended pressure and check the compressed air supply line for leakages; the air compressor should be working properly.

What to do if an INVALID configuration error message is displayed on my Donaldson Torit STi ODC-TC?

  An 'INVALID configuration' error on your Donaldson Torit Timer indicates a communication problem with the extension cards. Start by reviewing the DIP switch configuration on the extension cards, ensuring they match the setup in Section 2.2.2 Step 2. Next, check that the CAT5 cables connecting the extension cards to the master card, and between extension cards, are securely fixed at both ends. Also, check the integrity of the CAT5 cable and replace it if necessary. If problems persist, the master and/or extension cards might be damaged and require replacement; provide the timer's serial number and QC sticker details when requesting a replacement.

Why does my Donaldson Torit Timer pulse valves immediately after turn on but not after a while?

  If your Donaldson Torit Timer pulses valves immediately after being turned on but then stops, it could be related to the offline cleaning feature. As a first step, temporarily disable offline cleaning via the Offline Cleaning Cycles Selection screen (Figure 42). Turn off the timer, wait at least 90 seconds, and then restart it. If the timer now works correctly, ensure the connection between the auxiliary contacts on the fan and terminals J11 is secure. If you do not intend to use the Offline Cleaning feature, bridge the contacts of terminal J11.

What to do if valves are not pulsing on my Donaldson Torit STi ODC-TC Timer?
- J
  John GutierrezNov 10, 2025
  If the valves on your Donaldson Torit Timer aren't pulsing, several factors could be at play. First, ensure the timer is receiving adequate power at the rated voltage. A low voltage might power the display but not the valves. Check the cable connections at terminal J4 for AC power or J7 for DC power to confirm they are secure. Also, inspect the CAT5 cable linking the extension cards to the master card for secure connections. Make sure that pulsing hasn't been paused manually (return to Automatic or Pulsing Mode) or by an interrupt signal (deactivate the signal). If a pulsing disable alarm has been triggered, power down the dust collection system and fix the issue before restarting. Note that if the timer is in Automatic Mode and the differential pressure is below the high set point, this...
