PROGRAMMING AND OPERATION
The 777-P2-DEMO and optional accessories must be programmed prior to first use. Select the
operating parameters by following the instructions below.
1. Rotate MODE SELECT to the parameter to be programmed. It is recommended that LV be
programmed first.
2. Press and hold the RESET/PROGRAM button.
3. While holding the RESET/PROGRAM button, rotate the DISPLAY/PROGRAM knob until the
proper setting for the parameter that is being programmed is displayed.
4. Release the RESET/PROGRAM button. This stores the new parameter in the nonvolatile
memory. If the number changes back to what it was before programming, then the tamper guard
is on and will need to be unlocked before programming can be completed (see Tamper Guard).
5. Move clockwise through the positions to complete the process. Continue steps 1-4 until all
parameters have been programmed.
6. To reset all parameters (except for Address and Communication Parameters) and to clear the
last fault history, see CLEARING LAST FAULT/RESETTING PARAMETERS section.
The operation of the Model 777-P2-DEMO is designed to mirror the fail-safe operation of a 777-P2.
This means when the voltage is within the programmed limits, the
777-P2-DEMO will run with no
faults displayed, showing real-time values while the MODE SELECT is in the RUN position. When
the unit senses a fault condition, the 777-P2-DEMO will display the fault condition. Once the unit
has been programmed, it is ready to operate. Turn MODE SELECT to the RUN position. The display
will show “run” alternating with a number for the duration of the restart delay time programmed into
RD1. Once the timer expires, the 777-P2-DEMO will display only the number the
DISPLAY/PROGRAM knob is pointing to. If something other than this is displayed, see the
Troubleshooting section for more information. If MODE SELECT is taken out of RUN, the 777-P2-
DEMO will display the setpoint value indicated by the MODE SELECT knob.
