2.19 DISPLAY ADJUSTMENT
Once the 269Plus has been installed and input power applied, the display contrast may have to be adjusted.
This adjustment has been made at the factory for average lighting conditions and a standard viewing angle but
can be changed to optimize the display readability in different environments. To alter the display contrast the
trimpot on the rear of the unit marked "CONTRAST" must be adjusted with a small slotted screwdriver.
2.20 FRONT PANEL FACEPLATE
The front panel faceplate is composed of a polycarbonate material that can be cleaned with isopropyl or dena-
tured alcohol, freon, naphtha, or mild soap and water.
2.21 SPARE INPUT TERMINALS
Terminals 44 and 45 are provided for an additional relay contact input. These terminals may be used to sense
the closure of a 52B contact of a breaker or equivalent normally closed auxiliary contact of a contactor to deter-
mine a motor “stop” condition by enabling the Spare Input to Read 52B Contact setpoint
Do not connect live circuits. Dry contacts connections only.
A twisted pair of wires should be used. Connection to the 269Plus is made via a terminal block which can
accommodate up to #16 AWG multi-strand wire.
