12.3 I-O function and KCM state indications
12.3.1 State indications
• RUN - Motor is running (speed feedback)
• DISA - Indicates the feeder is disabled and can not start.
Conditions are as follows:
– RUN ENABLE digital input is OFF. In this case, All START
commands are ignored. A start command is required after the
digital input is cleared. Pressing START will generate alarm 42 -
"Start Ignored". This function can be programmed to any digital
input. Run Enable input issues a STOP command when de-
energized.
– DRIVE ENABLE digital input is disabled. This digital input is
enable from JU1 on the Motor Drive board (jumper terminal 3 to
4 AND 5 to 6). If disabled, all
START commands are ignored. A
start command is required after the digital input is cleared.
Pressing START will generate alarm 42 - "Start Ignored". This
input is predefined by JU1.
– DOWNSTREAM INTERLOCK digital input is active (ON). If a
START command is issued, “WAIT” is displayed. See “WAIT”
indication below. This function can be programmed to any digital
input.
• ALSH - Indicates the Alarm shutdown digital input is high. All
START commands are ignored. A start commend is required after
alarm shutdown digital input is cleared. This function can be
programmed to any digital input. Run Enable input issues a STOP
command when activated.
• WAIT - Start command is issued, but feeder cannot run. This can
be from setpoint = 0, feed factor = 0, or the DOWNSTREAM
INTERLOCK digital input is active. The start command is NOT
ignored and the feeder will run when the conditions are cleared.
• {blank} - If no status is displayed, the controller had a STOP
command and all other conditions are cleared.
Notes:
• A START and STOP command can be issued from the K-Tron
operator interface, Digital Input, or host communications.
• Run Enable, Drive Enable, and Alarm Shutdown inputs issue a
STOP command when activated. A Start command must be issued
AFTER the inputs are cleared for the feeder to run.
• In “Normal Mode“ not energized = OFF, energized = ON
In “Inverse Mode“ ON/OFF are reversed.
• Downstream Interlock requires an initial Start command. Toggling
this digital input does not
issue a STOP command and therefore
does not require a Start command. The exception is if a Stop
command is issued, a new Start command is required. If state is
