The displays do not illuminate. The unit is not connected to an
AC power source. Connect the 100 to a power outlet.
The fuse is blown. Replace the fuse.
Dipping does not start
immediately at an individual
position. Delay is programmed for the
position in question. Reprogram the delay.
The optional Report Center
Printer does not function. The printer is disabled. Program a print frequency other than 000.
Turn on the printer. The Ready LED
illuminates.
The Report Center Printer
functions, but nothing appears on
paper. The ribbon is exhausted. Replace the ribbon cartridge.
The water does not circulate. The tubing or pump is clogged. Remove the back panel and inspect the tubing
from the water bath to the pump. Remove the
tubing from the pump and inspect the inlet of
the pump for debris.
The pump is faulty. Contact the Dissolution Systems Service
Department for assistance.
The OverTemp light remains on. The water bath level is too low. Add water to the water bath.
Air is trapped in the tank or lines. Attempt to prime the system by raising and
lowering the front and rear of the instrument.
The temperature probe may be in
the wrong position or faulty. Inspect the position and condition of the
water bath temperature probe. Ensure the
probe is plugged into the 100. Check the
position of the probe within the water bath
and ensure it is fully submerged.
The temperature probe should only be used to
measure the water bath temperature. Faulty
readings occur if you use the probe in any
other manner.
