This Chapter describes the operation for the collection hopper.
1. Jet Clone type limit or level switch control collection hopper
1) Description of operations
Set the control panel power circuit breaker to ON.
↓
When the equipment starts conveyance by the start of
operation, the blower starts rotating in response to the
request signal from the limit switch. At the same time, the
collection hopper gate closes.
↓
Material is conveyed to the collection hopper of the period
of time set by the conveyance timer.
↓
When the conveyance timer has run out, the blower stops.
As the suction pressure decreases the collection hopper
gate opens to discharge material into the lower receiver
hopper for the period of time set on the discharge timer.
↓
The above operations are repeated.
In a case where respective request signals from multiple
conveyance directions are simultaneously sent, the
material is conveyed in the order of No. 1
→ No. 2 → No. n
→ No.2, alternatively.
When the receiver hopper has become full, the collection
hopper limit switch (in the case of limit control) or the
receiver hopper level switch (in the case of level switch
control) senses the condition to stop conveyance.
When a request signal is sensed again, conveyance is
started.
