Window switch mode programming instructions:

1 – With power off, set the two switches to 0 and the Input Signal Pulse Per Revolution to Low Range 0.5 pulse per mile (as
shown in the image below)
2 – Turn Power on to RPM-002 switch.
3 – Red LED will blink once per second for 30 seconds.
A – If RPM-002 is in Window Mode already the Red LED will go out and remain out until power is removed. When
the Red LED goes out the RPM-002 is returned to Normal RPM Switch mode. Set to the desired RPM and Pulse
Frequency/RPM Range and turn power back on.
B – When entering RPM Window Mode of operation the Red LED will begin to blink 5 times per second. Do NOT
move the Pulse Frequency/RPM Range Select Switch before setting the RPM switches.
1 – Set the RPM Programming switches to the desired low RPM setting.
IMPORTANT – Low RPM must be in the range 400 to 9,900 RPM.
2 – Once you have set the Desired Low RPM set the Pulse Frequency/RPM Range Select Switch to a non-zero
position.
3 – At this point the Low RPM setting will be checked for a valid setting. If the Low RPM is below 400 RPM or
Above 9,900 RPM the Red LED will blink alternating between Fast and Slow to indicate an Error.
4 – If the Low RPM setting is valid the RPM-002 will now enter Window Mode and the Low RPM setting will be
saved along with the new operating mode.
5 – The Red LED will now blink a pattern to show the Low RPM setting. Example – LED will blink twice, wait 1
second then blink eight times to indicate a setting of 2,800RPM.
6 – Turn power off.
7 – Set the Pulse Frequency/RPM Range Select switch to position needed for your application.
8 – Set the RPM Programming Switches to the desired High RPM setting.
IMPORTANT – High RPM setting must be greater than Low RPM setting.
9 – Turn power ON, The Red LED will blink the current Low RPM setting and then come on steady and the RPM-
002 is ready for Window Mode operation.
IMPORTANT – If power is removed while in the process of changing operating modes the new settings may become
corrupt. On power up the RPM-002 will check for valid settings and will default back to Normal Operating mode if an error
has occurred.
