b. If it has been running for at least that amount of time,
check to make sure the solvent sensor trigger set point is
correct. Using an Administration or Maintenance access
card, go into the Hood Status menu and scroll down to
the “Semicon Sensor” sub menu. Confirm that the “Trig.
M” value (e.g. 3600 mV) matches the GFH Settings sheet
that was provided with the hood.
c. Sometimes the sensor tubing is not properly connected
to each and every fan box. Have the customer remove
the front access panel and confirm that the clear tubing
coming from the Command Module is connected to the
first fan and each fan after that (fan quantity depends
upon hood width).
d. Cycle power with the fuse holder or unplugging the hood
to see if that resets the issue. The hood will re-boot, be
patient.
e. If the hood is still in saturation alarm, refer to tech support
at Erlab or Labconco as appropriate.
6) “The hood is in mis-match alarm (9A), why?”
a. The Command Module scans each electrical device
periodically to make sure it is still connected and working
properly. Sometimes, due to the timing of the scan, it
does not see a component and sounds the mismatch
alarm (code “9A”).
b. First, cycle power with the fuse holder or unplugging the
hood to see if that resets the issue. The hood will re-boot,
be patient.
c. If the mismatch alarm persists, have them insert the
Maintenance access card and press the OK button with
the cursor next to the “Hardware Mismatch” menu on the
screen. See step 1 of the Re-configuration Process in
the User’s Manual, pages 29-30.
d. Have them double check that the electrical connection to
the missing component is complete (fan, light, sash
sensor, etc.). Unplug and plug back in the connection.
e. Note: the alarm will not automatically clear. You must
reboot the hood (fuse or power cord) to get the
Command Module to rescan and clear the alarm.
f. If the hood is still in mismatch alarm, refer to tech support
at Erlab or Labconco as appropriate.
Note: To conclude, these six tech support scenarios represent over 95%
of the calls we receive. If, however, the customer cannot resolve the issue
(or is experiencing an issue not listed above) please don’t hesitate to get
tech support at Erlab and/or Labconco headquarters involved immediately.
