To Start and stop the Controller Two independent methods are provided. They are as
follows:
1. The first method will consequently stop the sequence and reset the controller to the initial
valve position whenever A. C. power is detached and then again reconnected.
2. The second strategy is by a remote control contact associated with the terminals provided.
At the point when the remote contact is opened, the execution stops. When the remote
contact is released, the execution proceeds from the previous.
Solid State Dust Collector Controller Operation:
The inventory SQP-1 sequential controller gives coordinated sequential energization of
associated loads. The “Power On” light emitting diode (LED) gives visual indication and the pulse
valve number 1 is immediately charged, when power is applied to the Controller. LED provides
visual indication of this event as “Output 1”.
For the length of time as indicated by the setting of the “On time/ Pulse Duration” control, the pilot
valve will remain energized. Note that the aligned dials are for estimated settings only and they
must be measured, if exact times are required.
Pilot valve number 2 will consequently be charged at some time span after pilot valve number 1
has been discharged. This time span will be as shown by the setting of the “Pulse Frequency / off
time” control. “Output 2” LED will give appropriate visual indication that this function is occurring.
The Controller will continue to sequentially energize the pilot valves until the power is detached.
For feedback type Extra Parameters are as follows:
A] 1) Potential free ‘NO’ relay contact- System Ok / Timer Healthy.
2) Potential free ‘NO’ relay contact- Sequence ‘ON’ / D.P. Low.
