APPENDIX I
– Wet Precipitator Wash Down System (Optional Feature)
Wet Precipitator Wash Down System Timer
If this control is being used in conjunction with a wet electrostatic
precipitator with a wash down system, optional relays on the Interface
Unit and relay timers designed into the Keyboard and Display Unit can be
used to control the wash down system.
First, from the Device Selection Screen press the Help key and the Enter
key until the Coordination System screen appears. Enter 1 to enable the
Coordination System, and then set-up the start and end ID numbers for
the coordination. Refer to Coordination System screens on page 28.
The automatic wash down system consist of the following timers:
1. Wash-down Interval
2. Wash-down Delay
3. Wash-down Duration
4. Drain Delay
These timers and the programming sequence for setting them are as
follows:
Press the PROMPT key and then the
key until the “Wash-down
System” Prompt Screen appears.
Press ENT
ER and the ‘”Wash-down Interval” Parameter Screen will
appear.
The wash-down interval is the time between wash-downs in hours,
minutes, and seconds. If the TR control is in the run mode when the
Interval timer expires and the Wash Duration starts, it automatically stops
firing the IGBTs and opens the contactor. If the TR control was off when
the Wash-down Interval expires, it will remain off when the Wash
Duration is complete.
The Range of this timer is one second to 99 hours, 59 minutes, 59
seconds. The present operating value for the Wash-down Interval is
presented to the right of the word “Enter”. In this example the present
operating value is 1 hours, 26 minutes, 4 seconds.
If the operating value is to be changed, simply press the numeric keys
corresponding to the new value (the old value will be overwritten) and
press ENTER. If the present operating value is acceptable, simply press
ENTER without making any changes. Either way, the display will now
change to the Wash-down Delay display.
