Display Information:
On starting up: The display briefly turns all segments on and then shows the trip setting.
During normal operation: If the starter is on but the AC is not running, OLP 3+ displays the voltage (as a
3-digit number without a decimal place). When the AC is running, the display switches to showing the
current being drawn by the AC, in amperes, with one place of decimal. The below examples might be
useful:

1. Voltage being displayed.
If an unsafe line voltage is present, preventing your AC from being allowed to start, OLP 3+ will display
the line voltage alternated with "Hi" or Lo", indicating that the voltage is too high or too low respectively.
During TIMECHECK: TIMECHECK is active when OLP 3+ is restarted or has tripped due to
VOLTCHECK or AMPCHECK and less than three minutes have passed since the compressor was
last turned off.

If AMPCHECK caused OLP 3+ to trip, the dashes will alternate with a display of "OL" and the fault
current in amperes, indicating an overload.
If VOLTCHECK caused OLP 3+ to trip, the dashes will alternate with a display of "Hi" or Lo" and the
fault voltage which caused the trip.

Installation instructions:
Insert wire terminals (copper only) and tighten all screws
fully to avoid loose connections and fire hazards.
SCPD/MCB must not be rated higher than 32A.
If required, a hole can be drilled through the front platefor
passing the AC's power cable. There is a provision made
for this in the back plate to the left side of the terminals.
The AC should be Earthed directly. OLP 3+ does not
require an Earth connection.
