2. Shutdown-set-times blowing function
The controller is set up with an input switch signal for shutdown blowing
control of the dust removal system. When the shutdown input signal contact of the
system is closed, after completing this cycle, the control device will continue blowing
the set times and then stop working.
※ When customers do not use this function, the signal lines must be
disconnected.
3. Poppet valve control function
Poppet valve is used to control the automatic cleaning door and cylinder of dust
removal system (this feature is only applied on controllers with AC220V and AC110V
output). The control number of poppet valve can be arbitrarily set, the maximum set
number is the one that total channels minus blowing pulse valve channels, and it can
be set in group.
4. Blowing channels setting function
The control device can arbitrarily set the blowing channels (set channels ≤
total channels)
5. Blowing time setting function
The control device can arbitrarily set the blowing time and the opening time of
pulse valve in the range of 10ms ~ 2500ms.
6. Blowing time interval setting function
The control device can arbitrarily set the blowing pulse valve and the time
interval of blowing pulse valve in the range of 1S ~ 250S.
7. Blowing cycle time setting function
Customers can set the blowing cycle time, the time interval between the first
blowing ends and the second blowing starts, according to the requirements of dust
removal, in order to achieve the goal that the dust removal system operates more
economically and energy-efficiently.
8. Repeated blowing (continuous blowing in single channel) function
The controller can be set to blow a single channel continuously to clean bags
with more dust.
9. Output short circuit protection function
If short-circuit appears in the output circuit, the control device can automatically
skip the output short circuit, while other circuits continue the cycle work. When the
short-circuit fault is removed, the output circuit will involve in the blowing cycle by
itself.
IV. Work mode selection
1. Pulse valve mode (No poppet valve, pressure switch, shutdown-set-times
