• Remove pull tabs from the batteries to power up the 8150.
• Observe polarity! Note that both batteries should face the
same direction.
• When the “low battery” indicator appears on the display, both
batteries should be replaced within 90 days.
• Remove and replace battery #1 fi rst, then remove and replace
battery #2.
This ensures that all settings and totalizer values are saved.
• If the low battery symbol reappears for more than 10 seconds
after installing new batteries, one battery is reversed, or battery
#2 was installed before battery #1.
• Secure the batteries by fastening the hook-and-loop straps.
4. Wiring
• The wiring is identical for the panel mount and the fi eld mount versions of the Totalizer.
• Only one wire should be inserted into a terminal. Splice double wires outside the terminal.
• External Reset for Total #1: Use no more than 30 m (100 ft) of 2-conductor twisted-pair cable connected to a dry contact
(for example, an ordinary door-bell button or relay contact).
• Only Totalizer #1 can be reset by the external connection.
• Total #1 will not be displayed unless it is the standard totalizer selection.
