Start Up
1. Go through the Pre-Operation Checklist in Table 7.
2. Turn the AC Power Switch on the EasyKey and on
the Power Supply Module ON (I = ON, 0 = OFF).
➜ Graco logo, software revision, and “Establishing
Communication” will display, followed by Status
screen. See page 20.
➜ At power up the system defaults to Recipe 61,
which is not a valid recipe number. Initiate a
color change to Recipe 0 or a valid recipe num-
ber (1-60).
➜ In bottom left corner, the system status displays,
which can be Standby, Mix, Purge, or an alarm
notification.

active recipe number should display and the
Standby LED
should be lit.
4. If this is the first time starting up the system, purge it
as instructed in Purging Fluid Supply System,
page 59. The equipment was tested with lightweight
oil, which should be flushed out to avoid contaminat-
ing your material.
