When crossing counter setting length, overlength alarm module is reminded, and folding and unfolding module is for controlling withdrawing rope, relay therein point
Do not connect with the A.C. contactor of motor, when relay normally opened contact closure when, motor start to work, folding and unfolding module with
It is provided with normally opened contact between the circuit of counter connection, when normally opened contact is opened, the folding and unfolding campaign of folding and unfolding module is counted
Device control, when normally opened contact closure, the Joint failure of folding and unfolding module and counter, counter no longer controls and send rope or rope closing.
Control section cooperation execution part has following operating mode:
Measurement pattern: first pressing reset switch, and counter is zeroed out, and presses SB1, the relay k1 connecting with SB1
It is switched on, the A.C. contactor closure on the motor connecting with k1, motor is started to work, while being measured gear 4 and being started to turn
Dynamic, the rotary encoder connecting with measurement gear 4 is started to work, and is sent result to counter, is handled and record through counter
It is rotated as a result, unclamping SB1 and stopping motor 12, the result of counter records is the length of put rope at this time.
Fixed length folding and unfolding mode: first numerical value is set on counter, next press SB1, start to put rope, this hour counter after
The length data that rotary encoder is sent is received in continued access, and the data being subject to are compared with setting value, when the two is identical
It waits, folding and unfolding module from service.
Forced working mode: when normally opened contact is closed, even if reaching counter set point can continue to put rope, the mode
It is easy to operate, it is especially suitable under the operating condition for not needing size operation, and rope length is actually put when counter setting numerical value is less than
When spending, it can quickly be adjusted by forced working mode, it is more convenient to use.
Embodiment as one preferred, the counter are six electronic digital display counters of high-precision.
Embodiment as one preferred, the counter are also connect with display device, and count results displaying is being shown
In device, it is easy to use.
