DEMIO overview The DEMIO 1 is an easy to program flexible starter panel designed to control one motor. The DEMIO features are: Three independent programmable timers; START DELAY, RUN TIME and STOP DELAY, each with modifiable units (seconds, minutes or hours), ...
10/30/2006 Operation of the panel (AUTO mode) Start/Stop signals In automatic mode, the DEMIO control panel starts running when a start signal is received and stops running (or executes the STOP DELAY) when a stop signal is received or when the RUN TIME is reached.
Alternating cycle An alternating cycle executes a pause after every ALTERNATING CYCLE RUN period. If a RUN TIME is programmed, it will continue counting during an ALTERNATING CYCLE PAUSE. Both RUN and PAUSE timers must be programmed for this function to be active. See example of operation below.
10/30/2006 Alarms When the system is stopped due to an alarm, the Alarm indicator will flash and the alarm code (A1 or A2) will be displayed OR the detected amps will be displayed and the corresponding parameter’s indicator will flash (see the figure below for a FULL LOAD alarm).
Setting the full load amperage The full load amperage functions as an electro-mechanical overload yet with a much better precision and sensitivity. A maximum load alarm will halt the system due to amperage exceeding 1.3 times the FULL LOAD AMPERAGE (FLA) parameter for more the 5 minutes or 2 times the FLA for more than 10 seconds.
10/30/2006 Setting the minimum amperage 1. Press the MENU key to enter the menu on the left of the panel. The indicators on the right of the menu indicate which menu is active. Press the MENU key to scroll down to the MINIMUM AMPERAGE parameter.
Programming the timers 1. Press the MENU key to enter the menu on the left of the panel. The indicators on the right of the menu indicate which menu is active. Pressing the MENU key again will scroll down the menu. 2.
10/30/2006 Programming an alternating cycle 1. Press the MENU key to enter the menu on the left of the panel. The indicators on the right of the menu indicate which menu is active. Press the MENU key again scroll down ALTERNATING CYCLE, RUN parameter.

5. Press MENU to jump to the PAUSE parameter. 6. To modify this parameter, press the PROG Key. The unit indicator will flash. Use the arrows to choose the time unit. Press PROG a second time. The value of the PAUSE timer will flash.
10/30/2006 Programming the maintenance frequency 1. Press the MENU key to enter the menu on the left of the panel. The indicators on the right of the menu indicate which menu is active. Press the MENU key to scroll down MAINTENANCE FREQUENCY parameter.
How to reset an alarm To reset an alarm simply press the STOP/RESET key. How to reset a maintenance warning To reset a maintenance warning, simply press the HOUR METER key. Press and hold the HOUR METER to view the cumulative running hours.
10/30/2006 How to view the cumulative running hours The HOUR METER displays the total cumulative running hours of the motor. The displayed time is divided by 10 (ex. 12 displayed = 120 hours). Press and hold the HOUR METER key to view the cumulative running hours.
How to lock the configuration If the panel is installed in an area where inexperienced users may have access to the panel, it is recommended to lock the panel’s parameters from modification. The following procedure will lock the PROG key. 1.
10/30/2006 Advanced function 1: Max amperage delay The full load amperage (page 6) functions as an electro-mechanical overload yet with a much better precision and sensitivity. A maximum load alarm will halt the system due to amperage exceeding 1.3 times the FULL LOAD AMPERAGE (FLA) parameter for more the 5 minutes or 2 times the FLA for more than 10 seconds.
Advanced function 2: Number of wounds (current transformer) The advanced function 2, number of wounds, is normally factory set and should only be modified if recommended by the manufacturer or dealer or when replacing the electronic circuit board. This parameter configures the amperage meter to function with the proper electric configuration of the control panel and depends on the maximum amperage value of the panel.
