The keys are used for alpha-numeric data entry.
In many circumstances where only use of the arrows keys are indicated, the number
keys work equally as well for data entry.

Key Functions
Auto-Repeat
In some screens where you are adjusting values, you may find it helpful to press and
hold an arrow key. After a brief moment, the key will repeatedly issue it’s command
giving you a quick way to scroll through a broad range of values.
Turning Relays On/Off from the front
panel and front panel overrides
Pressing the Relay Button enters relay control mode. When in this mode, the
following keys can be used
• Use to adjust the relay number (number keys can also be used, but 2
digits are always required)
• Use to adjust the relay state, UP for ON, DOWN for off.
• Pressing (up arrow twice) puts the relay into an override ON state.
When in this state, no other relay panel function can alter the state of this relay
other than the front panel. (Only one arrow press is required if relay is already
on.)
• Pressing (down arrow twice) puts the relay into an override OFF state.
When in this state, no other relay panel function can alter the state of this relay
other than the front panel. (Only one arrow press is required if relay is already
on.)
• Pressing Select when in either override on or off mode will allow you to enter
a time and then activate Timed Override mode by pressing Select again. A
timed override forces the relay into the ON (or off) state for the elapsed period
of time. Once the time expires, the relay returns to the function indicated by
other controlling devices, or off if none are indicated.
