START SIGNAL (blue, yellow, violet)
This will flash when a machine control start signal
is commanded; blue denotes Probe 1 start, yellow
denotes Probe 2 start and violet denotes Probe 3
start.
A successful probe start will cause the ‘ACTIVE
SYSTEM’ LED to become lit and a failed start will
result in an ‘ERROR’ being displayed.
ACTIVE SYSTEM (blue, yellow, violet)
In single probe mode the system will be constantly
lit blue to show that the input is active.
In multiple probe mode the system will be
constantly lit blue to denote Probe 1 is active,
yellow to denote Probe 2 is active and violet to
denote Probe 3 is active.
If any ambiguous start information is received, the
system will flash repeatedly (blue – yellow – violet
– cyan) in sequence until the start input is cleared.
ERROR and STANDBY (red)
When lit constant red it indicates a transmission
error condition, such as optical beam obstructed /
probe out of optical range / probe switched off
(standby) / dead battery.
OVERCURRENT (ashing red)
The system will start flashing red when an output
overload has occurred. All outputs will be switched
off.
If this occurs, turn off the power and remove
the source of the problem. Turning on the power
supply will reset the system.
CORRUPTED SIGNAL (white)
If the system displays a constant white LED, then
either a second modulated probe signal has been
received or the probe trigger instant has been
delayed due to interference or a weak probe
signal.
NOTE: In single probe mode the constant white
error condition resulting from the loss of a good
probe signal will persist until the machine start is
activated or 1 hour has elapsed. In multiple probe
mode the indication will persist until the active
system input (Probe1, Probe 2 or Probe 3) is
deactivated.
