Function
Explanation
Interlock
The two pushbuttons are interlocked; it’s not possible to
operate two opposite functions at same time.
Non-Interlock
The two pushbuttons can be operated at the same time:
When the application allows operating at the same time
two functions which are usually opposite to one another.
Interlock Delay
Time
"Interlock Delay Time" is delay time between 2 opposite
pushbuttons is being press one after another. i.e.: while
crane is moving one direction (forward), moving opposite
direction (backward) immediately would be dangerous
especially when crane is hooking up the heavy object.
The object may sway if crane does not completely stop
before moving into opposite direction. Therefore the
interlocked delay time could potentially prevent it.
Normally, the interlocked delay time should be larger
than the duration of crane stop.
Acc. Delay
This function uses to set the time interval between
acceleration relay (i.e. conduction-delayed time of
acceleration relay) . I t is suitable f or accelerative
operation only in order to prevent the cranes directly runs
to highest speed to damage the motor.
Two speed
Control
Through the software setting, F21-E2 remote controller
allows to use A and B two single-speed buttons to
proceed two-speed simulation control. In this way, the
flexibility and cost savings can be substantial increase.
Dual motor
Control
Through the software setting, F21-E2 remote controller
allows to use A and B two single-speed buttons to
proceed dual motor simulation control. In this way, the
flexibility and cost savings can be substantial increase.
Inching
The relative relay will be conducted within a certain time,
in order to operate with short and precision movement.
There are two kinds of inching modes:
Normal Inching
: Turn the rotary key switch (KEY) to
"START" position and hold it, then press the relative
motion pushbutton to perform inching motion. (When "
Normal Inching" is chosen.)
Toggle Inching
: Turn the rotary key switch (KEY) to
"START" position, then it can perform inching motion.
