tens digit and the DS4 LED will then display the ones digit. For example to display 54, the DS3 LED will flash 1 group of 5 at a high flash rate to indicate 50, and then follow with 4 flashes (DS4) at 1-second intervals to complete the display of the number 54.

NOTE: Do not try to count the “5 Fast Flashes” individually, but instead count how many groups of 5 flashes were displayed. In this case, 1 group of 5 flashes, plus the 4 flashes at 1 second results in the value of 54.

To read the display again, push the READ/ADJUST (#1) but- ton and the sequence will repeat as many times as needed.

To advance to the next setup point, push the ADVANCE/ MANUAL (#2) button. The controller will cycle through all the setup channels (Table 34) and then the I/O channels (Table 35) and then back to the first setup channel.

date or serial no

NOTE: The user can only advance forward, not reset to #1 or go backwards. Cycling the EconoMi$er+ power will reset the item number (but not the item value) to item #1.

In the Read mode for setup variables, the LEDs will not turn on steady; the LEDs will always flash. Steady-on indicators are reserved for the configuration modes. No data is modified in the Read mode. The controller will always remain at the last read number even if reset back to normal operation.

NOTE: To enter another mode, the user first must exit the Read mode.

If no button is pushed in 10 minutes, Read mode will auto- matically be exited. Also, if the READ/ADJUST (#1) and ADVANCE/MANUAL (#2) buttons are pushed and held for more than 3 seconds, then Read mode will be exited to Run mode. While in the Read mode, the controller will continue to operate with normal unit control.
