Sequential Controller
|
| |
Sequential Controller designed by MANIKS,
to operate the MANIKS pilot valves used on dust collector equipment. Light emitting (LEDs) provide visual indication
of which pilot valve is being energized as well as "Power
On" indication. The number of sequenced steps is
adjustable from 2 through 10.
Controls are provided to adjust the
length of time between valves being energized (Pulse
Frequency) and the length of time that the valve is
energized (Pulse Frequency) . Silicon semiconductor
components control all timing and logic functions.
Two independent methods of starting
and stopping the Controller are provided. The first
method will automatically stop sequence and reset the
Controller to the first valve position whenever A.C.
power is removed and than reconnected.
The second method is by a remote control
contact connected to the terminals provided. When the
remote contact is opened , the sequence stops, When
the remote contact is reclosed, the sequence continues
from the previous position.

| Field Wiring Procedure |
A 15-point terminal block with
approved means for connection of conductors without
terminal lugs are provided on the Controller for convenient
wiring of the control power, loads and remote contact
(if used).  Figure 1 illustrates where all necessary
wiring should be made, loads, should be wired in desired
sequence as noted. ONLY after all connection has been
re-checked, should power be applied to the Controller.
NOTES
1.When remote contact is used, jumper between Half (P1
&P2) must be removed.
2.Number of sequenced steps adjustable in field by moving
jumper wire. |

OPERATION
The sequential Controller provides timed sequential
energization of connected loads. When power is applied
to the controller, the "Power" light emitting
diode (LED) provides visual indication and loan number
1 is immediately energized. Output 1" LED Provides
visual indication of this event. The load will remain
energized for the length of time as indicated by the
setting of the "Pulse Duration" control. Refer
to Figure 1. Note that the calibrated dials are for
approximate settings only and if exact timings are required,
they must be measured.
Load number 2 will automatically be
energized at some time interval after load number 1
has been deenergized. This length of time will be as
indicated by setting of the "Pulse Frequency"
control. "Output 2" LED will provide visual
indication that this event is occurring. The Controller
will continue to sequentially energize the loads until
the power is removed.
Two independent methods of starting
and stopping the controller are provide. This first
method will automatically stop the sequence and reset
the Controller to the first load position whenever the
A.C. Power is removed and then reconnected. This can
be accomplished by placing a control in the line conductor
connected to terminal "1".
The second method provides for remote
starting and stopping of the Controller. To accomplish
this the factory supplied jumper connected between terminals
P1&P2 must be removed and a remote control contact
wire, in its place as shown in figure 1. When this remote
contact is closed, the Controller will sequentially
energize the loads. When the remote contact is opened,
the sequence stops. When the remote contact is reclosed,
the sequence from the pervious position.

ADJUSTMENTS
CAUTION: Switch off the controller before making any connection
or adjustments.
|
| To
CHANGE TIME INTERVALS |
TO
CHANGE NUMBER OF LOAD STEPS |
Turn
the Pulse Frequency dial To the desired setting.
This is the
Approximate time interval between
Energizing load steps. Turn the
Pulse Duration dial to the desired
Setting. This is the approximate time Interval
that each load is energized. |
Locate
the Jumper wire connected between the circuit
board and the step pin. pull off the jumper and
push it into the desired pin number. This is the
total number of load steps. |
