4.2.2.3 ON/OFF Pushbutton Function
The user can set any of the two adjacent
pushbuttons on the transmitter to behave like a
mechanical ON & OFF rocker switch (
see Section
4.2.4 on page 39
on how to set to this function).
When the ON output relay is closed (ON
pushbutton pressed), the OFF output relay will
open automatically, or vice versa.
4.2.2.4 START/AUX Function (EX System only)
After initiating the START function, the START position will become an auxiliary
function with momentary contact. For auxiliary applications such as a horn or a
buzzer, connect it to the FUNC output relay (wire #6) located inside the receiver unit.
4.2.2.5 Brake Function (EX System only)
When the transmitter pushbutton is released from 2nd speed up to 1st speed, both
1st and 2nd speed output relays will open for up to 1 second and then with 1st speed
output relay closed thereafter (
see Section 4.2.4 on page 39
on how to set to this
function).
4.2.2.6 Momentary Contact (EX System only)
When the pushbutton is released, the output relay that corresponds to that
pushbutton will open (
see Section 4.2.4 on page 39
on how to set to this function).
This type of contact usually applies to external applications such as horns or
buzzers.
4.2.2.7 Toggled Contact
When the pushbutton is released, the output relay corresponding to that pushbutton
will remain closed (maintain contact) until the next time the user presses the same
pushbutton (
see Section 4.2.4 on page 39
on how to set to this function). This type
of contact is usually applied to external applications such as lights.
4.2.2.8 3rd Speed Pushbutton Function (EX System only)
This function allows the crane to travel an
additional step beyond 2nd speed. For example, if
the operator is pressing the UP pushbutton down
to 2nd speed, pressing the 3rd speed pushbutton
(with UP pushbutton still held at 2nd speed) will
toggle between 2nd speed and 3rd speed (
see
Section 4.2.4 on page 39
on how to set to this
function).
4.2.2.9 Auxiliary STOP Pushbutton Function (EX System only)
The auxiliary STOP function acts as a 2nd
emergency stop button. Other than by emergency
stop button and transmitter power key switch, the
receiver MAIN is also deactivated when this
auxiliary stop pushbutton is pressed (
see Section
4.2.4 on page 39
on how to set to this function).
