Calibration
3515 Speed Alert Control Unit –Setup Procedure
If the installed location of the speed alert control unit has made the on-board push button inaccessible, the
blue wire can be used as a substitute. In this case, replace the statement ‘press the push button’ with ‘bridge
the blue wire to earth (0 V)’ in all instances in the following instructions. Also replace the statement ‘while the
button is pressed’ with ‘while the blue wire is bridged to earth’.
When in programming/setting mode as shown below, all frequency settings are half the actual required value.
As an example if 18 km/h (750 Hz) is required then the trip frequency should be set to 9 km/h (375 Hz). When
the power is cycled at the completion of programming, the trip frequency will be 18 km/h (750 Hz).
Note
To set the trip frequency and release points for relays 1 and 2, the program code 012 must be entered.
To enter program code 012:
1. Select 0on the HEX rotary switch and press the push button for one second, this will be acknowledged by
the status LED staying on while the button is pressed
2. Select 1on the HEX rotary switch and press the push button for one second, this will be acknowledged by
the status LED staying on while the button is pressed
3. Select 2on the HEX rotary switch and press the push button for one second, this will be acknowledged by
the status LED staying on while the button is pressed
When the program code 012 has been entered, the status indicator will start flashing every six seconds.
If the indicator does not flash every six seconds, cycle the power to the unit and repeat steps 1 to 3.
Setting the trip and release frequencies (note that relay 1 is usually for pre-alarm if both relays are
being utilised):
1. Select 1on the HEX rotary switch to select relay 1 trip frequency. Drive the machine to 50% of the desired
pre-alarm speed and set the resulting frequency by pressing the push button for one second. This will be
acknowledged by the status indicator staying on while the button is pressed
2. Select 2on the HEX rotary switch to select relay 2 trip frequency. Drive the machine to 50% of the desired
alarm speed and set the resulting frequency by pressing the push button for one second. This will be
acknowledged by the status indicator staying on while the button is pressed.
3. Select 3on the HEX rotary switch to select relay 1 release frequency. Drive the machine to 50% of the
desired pre-alarm release speed and set the resulting frequency by pressing the push button for one
second. This will be acknowledged by the status indicator staying on while the button is pressed
4. Select 4on the HEX rotary switch to select relay 2 release frequency. Drive the machine to 50% of the
desired alarm release speed and set the resulting frequency by pressing the push button for one second.
This will be acknowledged by the status indicator staying on while the button is pressed
5. Cycle the power by turning the unit off and then back on to save the settings. The unit is now set and ready
for a test run to confirm the new values
Important
If tampering has occurred and the 3515 control unit is not functioning correctly, then a factory restore may be
required. To do this, program code 06C must to be entered.
To enter program code 06C:
1. Select 0on the HEX rotary switch and press the push button for one second, this will be acknowledged by
the status indicator staying on while the button is pressed
2. Select 6on the HEX rotary switch and press the push button for one second, this will be acknowledged by
the status indicator staying on while the button is pressed
3. Select Con the HEX rotary switch and press the push button for one second, this will be acknowledged
by the status indicator staying on while the button is pressed
When the program code 06C has been entered, the status indicator will start flashing continuously. If this
is not occurring, cycle the power to the unit and repeat from step 1 (restore factory setting above).
4. Restore to factory settings by selecting 8on the HEX rotary switch, then press the push button for one
second. This will be acknowledged by the status indicator staying on while the button is pressed.
5. Cycle the power by turning the unit off and then back on to save the settings
