The Site Supervisor Display (P/Ns 818-9022 and 818-9023) is a remote user interface for the Site Super-
visor (P/N 860-1200) that connects to the controller using RS485 network to Serial Port D, and shows a sim-
plified UI that allows users to perform critical actions in the controller quickly and easily such as overriding
lights, heating and cooling stages, viewing alarms, and status information.
General Warnings and Safety Precautions
• This guide is part of the product and should be kept near the instrument for quick and easy reference.
• The Display should not be used for purposes different from those described in this guide. It cannot be used as a safety
device.
• Check the application limits before proceeding.
• Emerson Retail Solutions reserves the right to change the composition of its products, even without notice, ensuring the same and unchanged functionality.
• When using an external power supply, it is necessary to separate the power of the device from the rest of the electrical devices connected inside the electrical
panel. The secondary of the transformer must never be connected to earth ground.
• Disconnect all electrical connections before any kind of maintenance is performed. Do not open the Site Supervisor Display.
• Check that the supply voltage is correct before connecting.
• Do not expose to water or moisture: use the controller only within its operating limits to avoid sudden temperature changes with high atmospheric humidity to
prevent condensation.
• Wire polarity must be observed: A wrong connection may cause possible malfunctioning and damage to the controller or Display.
