VSX OPERATING MANUAL
attempts to restart whatever should be running,
every 30 seconds. It will continue this until the
overload condition is no longer detected. The
last station to have caused an overload is
displayed (###) in the message.
Pressing the ‘CLEAR’ key will clear this
message. If the overload occurs while you are
present at the controller, you can press CLEAR
to force the controller to immediately try to
restart, without waiting for the 30-second timer.
Generally, overloads are caused by too many
stations activated at once, or faulty solenoids or
wiring in field devices (valves and VIH sprin-
klers). Clearing the display does not solve the
problem. You should inspect the field solenoids
and wiring if this is a recurring problem.
FUSE OPEN!: This indicates that the fuse on
the power supply board (PSB) has blown. This
message remains on until the fuse is replaced.
The fuse is an AGC3, 3 amp, fast-blow only.
COLD START!: This indicates that the user
program memory has been corrupted, and was
automatically reset to default conditions. The
controller irrigation memory is completely
wiped out when this message appears, and must
either be restored from a central computer or
reprogrammed by hand. Pressing the ‘CLEAR’
key will clear this message.
Note: You can perform a Cold Start on the Field
Controller at the keypad, if you want to com-
pletely erase its memory and start over. The
sequence for this is to press CLEAR, SCHED-
ULE, 0, ENTER. This will clear the controller
memory, although the Time, Address, and PINs
(passwords) are retained.
POWER OUTAGE: This indicates that power
has been lost in the recent past. Pressing the
‘CLEAR’ key will clear this message.
Events at Max: This indicates that the
System Program station event buffer is full.
This area of the controller can hold up to 1000
events. Pressing the ‘CLEAR’ key will clear
this message.
Max Sta Running: The VSX controller can
operate a maximum of 20 stations at a time.
This message indicates that scheduled or
manual programs are attempting to operate
more than 20 stations simultaneously. Pressing
the ‘CLEAR’ key will clear this message.
PINs Reset!: This indicates that the
controller’s Personal Identification Numbers
have been reset to the factory defaults, and the
controller is no longer password protected.
Pressing the ‘CLEAR’ key will clear this
message. You will need to reprogram pass-
words (PINS) if you want to restore password
protection.
RAIN SHUTDOWN!: This states that the
controller will not run any automatic programs.
A command from a central computer or by
pressing OFF on the keypad will toggle this
feature on and off. See Rain Shutdown on
page 7.
SUSPEND WATERING: This indicates that
the controller has stopped all irrigation (but event
timers continue to time on any stations that are
scheduled to run). This mode is only initiated by
the central computer. It can be cleared at the
controller keypad, using the same procedure as
“Resume” after a Pause command (See Pause on
page 7). To clear, press OPTIONS once. The
display will then show:
