HOLD
Key
– When electrical readings are being viewed or recorded by hand from the
Electrical Reading Screen pressing the HOLD key will freeze the display. All the electrical
levels are now presented with the same time base. Pressing the HOLD key again places
the display back to normal. If the HOLD key is not pressed again, the screen
automatically returns to normal after 5 minutes.
HELP Key
– Displays the Technical Help phone number. Also provides the screens
necessary to set up the total number of devices communicating with an individual Keypad
and Display Unit and the ID of the Keyboard and Display unit. Screens for setting up the
timer relay coordination system are also presented under this key.
CODE key
–
Used for entry of a security code before most parameters and features can
be programmed.
To keep unauthorized personnel from changing the programmable parameter settings, a
security code is required to make changes to most control parameters. Without the
proper security code, it is impossible to program or make changes to most control
parameters and set points.
When a parameter’s Parameter Screen shows an icon of a padlock on the Enter line, it
means that a security code must be entered before the parameter can be changed. Two
padlock icons indicate that the control must also be in the stop mode to make a
parameter change.
The CODE key is accessible at the Device Selection, Device Status, Electrical Reading,
and Prompt Screens. If you are in the Parameter Screen press the ESC key. This will
back you up one screen to the Prompt Screen. Enter the appropriate security code, and
press ENTER a second time to return to the Parameter Screen.
If an invalid code is entered, the display will show “Invalid Code” for 3 seconds and then
revert to the screen that was present prior to pressing the CODE key.
To maintain the integrity of the security code system, the control will automatically clear
the code five minutes after the last key is pressed. It is recommended that the code be
cleared manually after program changes have been completed.
To manually clear the security access code:
Press the CODE key
Press 0 0 0 0
Press the ENTER key
PROMPT / DOWN key
–
Brings up the first programmable parameter into the Prompt
display. Pressing this key again will scroll down through the programmable parameters.
ESC key

programmer wants to ignore the data entered, or when returning from a parameter to the
normal display.
CLEAR ALARM key

Used without a security code to view alarms that may be present
for each individual ID/control. If an alarm is present, this key is also used to clear the
alarm from the alarm screen once the cause of the alarm has been eliminated.
ENTER key

Used to accept numerical data that has been programmed into the keypad.
DEVICE SELECT key
