The Index Control (Slave) should have the Forward/Neutral/Reverse switch in the Neutral position,
the Run/Stop switch in the Run position and the speed set to that desired during an index.
The Index Control (Slave) sends a “Ready” signal to the Cycle Control (Master) whenever its
Run/Stop switch is in the Run position, the relevant limit switch does not impede its Index Direction
and no error conditions exist. If the Cycle Control (Master) does not receive the Ready signal, it will
not permit the activation of a new automatic indexing cycle, or will instantly perform a controlled
shut down of an active automatic indexing cycle.
Automatic Index Cycle Details
This section refers to parameter settings and values. Details of accessing and changing these
settings and values can be found later in this manual under the section “Programming The
Automatic Cycle Parameters/Variables”.
1. The automatic cycle is initiated by placing the Run/Stop switch of the Cycle Control (Master)
in the Run position.
a. If the Cycle Control (Master) is receiving the Ready signal from the Index Control
(Slave) the cycle proceeds to section 2.
b. If the Cycle Control (Master) is not receiving the Ready signal from the Index Control
(Slave) the cycle aborts, resets and displays “End”.
2. The Cycle Control (Master) looks at the status of the limit switches on the cyclic device
(“KAT”
®
).
a. If a single limit switch is activated, the cycle will proceed to section 4.
b. If no limit switches are activated, the cycle will proceed to section 3.
c. If no limit switches are recognized, the cycle aborts, resets and “Er.4” is displayed.
3. The Cycle Control (Master) will look at the status of its Forward/Neutral/Reverse direction
switch.
a. If the switch is in either Forward or Reverse position the cycle proceeds to section 4.
b. If the switch is in the Neutral position, the automatic cycle will wait until either a
direction is manually chosen by this switch, or the automatic cycle is terminated.
4. The Arc Signal Relay is energized (using CN81 of the “Cycle Control”) and the “Travel
Motion Delay” timing cycle (“P. 1”) is initiated. The cycle then proceeds to section 5.
5. Upon completion of the “Travel Motion Delay”, the cyclic device (“KAT”
®
) starts to travel at
the speed set by its speed adjustment knob, in the opposite direction to that of its activated
limit switch. If neither limit switch is activated, it initially travels in the direction set by its
Forward/Neutral/Reverse switch. The cycle then proceeds to section 6.
6. The cyclic device will stop when it reaches its travel limit switch.
a. If the “Arc On/Off During Index” parameter (”P. 2”) is set to On, the cycle proceeds to
section 10.
b. If the “Arc On/Off During Index” parameter (“P. 2”) is set to Off, the cycle proceeds to
section 7.
7. Once the cyclic device (“KAT”
®
) has stopped, the “Crater Fill Delay” timing cycle (P. 3”) is
initiated. The cycle then proceeds to section 8.
