12. Cleaning Agent
It is recommended to use a liquid cleaning agent because some
powders take too long to go into solution. ESMA Inc. has liquid cleaners,
E589, E882, E484, etc., where it is recommended to use 2 to 4 cups per
tank load. Some general-purpose detergents may be all that is required
to clean your items. Depending on types of parts and debris to be
removed, some experimentation will be required with type of cleaners
and concentrations. Remember: Adding too much cleaning agent can
cause a problem with final rinsing of parts.
13. Power Modules 1 and 2
The Power Modules contain the six circuit boards, programmable
controller, fans, relays, RFI filters, etc. There are six lights, one per
circuit board (two on PM1 and four on PM2), to indicate if circuit boards
are operating. To check if all circuit boards are operating, open door
slightly when unit is ultrasonically cleaning: all indicator lights must be
ON. If a light is out, the corresponding circuit board will have to be
repaired.
14. Programmable Controller
An Omron CPM 1 programmable controller is used to control the
process. The unit has a flash memory backup without a battery.
The controller has indicator lights for inputs and outputs, which
are lit during process. The outputs are as follows:
Output
Controls
00
Primary solenoid
01
Ultrasonics
02
Drain solenoid
03
Dryer
04
Overflow Pump
05
Buzzer
06
Drain Pump
07 Secondary Solenoid
The Programming Console on cabinet door can be used to monitor
these outputs or change their values. To change their values ESMA
should be notified.
