Introduction:
The SpeedMaster is a test instrument designed to check the function and calibration
of all types of Synatel speed monitors. The system consists of the SpeedMaster hand
held instrument and PulsePilot transducer.
By inserting the PulsePilot between the target and speed monitor, the actual shaft
speed can be displayed. The unit can then override the signal from the target injecting
a speed which can be reduced (or increased) in 1% steps to allow the actual trip speed
of the sensor to be determined.
The SpeedMaster can also be used to calibrate Synatel sensors to any desired speed
if the automatically calibrated speed is not suitable.
Method Of Use:
1) Plug the PulsePilot transducer into the SpeedMaster instrument and press the
“Power On” button, the display will illuminate.
2) Place the PulsePilot transducer between the speed sensor and target.
IMPORTANT SAFETY NOTICE – When using the Synatel Whirligig speed
monitoring accessory the PulsePilot can generally be hand held even when
the monitored shaft is rotating. However all applications are different and great
care should be taken with regard to personal safety.
If a target system supplied by third parties is being used, the PulsePilot must
not be hand held. The shaft should be stopped and locked out. The PulsePilot
should then be attached firmly but temporarily eg with non metallic industrial
adhesive tape, guards refixed if appropriate and the system restarted.
Upon switch-on the SpeedMaster is in input mode and the input light will flash each
time a target is seen. The display will show measured speed in pulses per minute
(the Whirligig can have 1, 2, 4 or 8 pulses per revolution).
[Note: Pressing upper display button “-10%”, displays 90% of measured speed.
and Pressing lower display button “-20%”, displays 80% of measured speed].
3) Press the calibrate button, this will set the SpeedMaster internal oscillator to the
measured shaft speed, (or to 1000 P.P.M if the shaft is stationary).
4) Press the “Mode” button, the output light will flash and the calibrated pulse rate
will be fed to the sensor.
IMPORTANT SAFETY NOTICE – In this condition, the sensor is receiving
pulses only from the SpeedMaster, shaft pulses are not monitored and the
system should be observed for faults and shut down manually in event of a
fault occurring.
At this point, the speed can be artificially raised or lowered in 1% steps. Pressing the
“PPM/%” display button will toggle between actual speed or percentage reduction from
calibrated speed. Each press of the upper display button will increase simulated speed
by 1% and on the lower display button will decrease simulated speed by 1%. Holding
down either button will cause the simulated speed to increment/decrement simulated
speed in 1% steps.
The system should shut down when the calibrated ‘trip’ setting is reached, normally
20% under running speed.
When pressed, displays 90% of
measured speed.
MODE
INPUT OUTPUT
Power On, press once when PulsePilot is connected. Unit powers
off automatically if no buttons are pressed for 5 minutes. It can be
turned off immediately by unplugging the Pulse Pilot.
When pressed, displays 80% of
measured speed.
Sets simulated speed generated
by SpeedMaster to be equal to
measured speed.
Press to change to ‘Output’ mode.
No Function.
Each press increases simulated
speed by 1% of starting value.
Holding down increments speed
in 1% steps.
Each press reduces simulated
speed by 1%. Holding down
decrements in 1% steps.
No Function.
Press to change to ‘Input’ mode.
Toggles between simulated
speed in PPM and % of
calibrated speed.
