1. Confirm that all wiring for the PC has been installed and checked prop-
erly.

5. Turn on PC power.
6. Enter the password.
7. Clear memory.
Each of these operations from entering the password on is described in detail
in the following subsections. All operations should be done in PROGRAM
mode unless otherwise noted.
To gain access to the PC's programming functions, you must first enter the
password. The password prevents unauthorized access to the program.
The PC prompts you for a password when PC power is turned on or, if PC
power is already on, after the Programming Console has been connected to
the PC. To gain access to the system when the "Password!" message ap-
pears, press CLR and then MONTR. Then press CLR to clear the display.
If the Programming Console is connected to the PC when PC power is al-
ready on, the first display below will indicate the mode the PC was in before
the Programming Console was connected.
When the password is entered, the PC will shift to the mode set on the mode
switch, causing PC operation to begin if the mode is set to RUN or MONI-
TOR. You can change the mode to RUN or MONITOR with the mode switch
after entering the password.
Indicates the mode set by the mode selector switch.
Never change the PC operating mode or enter the password without first
confirming that it is safe to do so. Changing the mode or entering the password
can create dangerous or fatal situations when the controlled system starts or
stops as a result of changing the PC operating mode.
Immediately after the password is input or anytime immediately after the
mode has been changed, SHIFT and then the 1 key can be pressed to turn
ON and OFF the beeper that sounds when Programming Console keys are
pressed. If BZ is displayed in the upper right corner, the beeper is operative.
If BZ is not displayed, the beeper is not operative.
