Motor
Motor Jammed
1. This can be caused by debris inside the cell, a jammed cleaning ball or an internal failure of the
motor.
2. Turn the power off to the analyzer, shut off the sample water fl ow and drain the cell. Being sure to
catch the cleaning balls, unscrew and remove the probe assembly. Remove all cleaning balls from
the cell.
3. Attempt to turn the motor / striker assembly by hand. If a ball or other solid material is jammed in the
cell, it may be necessary to move the assembly back and forth to dislodge the jam.
4. If nothing is physically jammed in the cell, turn on the power to test the operation of the motor while
the cell is empty of water and cleaning balls to determine if the motor is damaged internally. Check to
be sure the striker is not rubbing against the cell wall or gasket(s).
Noisy Motor
1. The specifi c amount of noise that comes from the motor will vary somewhat from one motor to
another. But if the motor becomes noticeably louder, this most likely indicates a problem developing
in the cell or inside the motor.
2. Follow steps 2 and 4 from the previous section on “Motor Jammed” to identify the source of the noise.
3. If necessary, replace the motor.
*IMPORTANT NOTE: Do not attempt to disassemble the motor. It is encapsulated and is not
intended to be repaired in the
fi eld.
Motor is hot to the touch
The motor will always operate hot to the touch. The specifi c temperature of the motor will vary
depending on the air temperature. The motor casing temperature is expected to be 35 – 50 degrees
Celsius (60 – 90 degrees F Fahrenheit) greater than the air temperature.
Reagent Feed System
Reagent feeds too slowly
1. This is caused by debris entering the star wheel assembly and partially obstructing the reagent fl ow.
2. The star wheel assembly can be carefully disassembled and cleaned / fl ushed out with clean water.
Be careful not to scratch the star wheel surfaces or to touch the inner surfaces with any abrasive
material.
Reagent feeds too fast
1. This is caused by debris entering the star wheel assembly and becoming lodged between or
damaging the critical surfaces.
2. Replace the star wheel assembly.
Note that star wheel assemblies can be returned to Hydro Instruments for refurbishment.
