6.2 POWERING ON / OFF BY FEEDING EXTERNAL +12V SIGNAL TO
TERMINALS MARKED “REMOTE ON/OFF” ON THE FRONT PANEL
The unit can be switched ON /OFF remotely by feeding 2 specied formats of +12VDC (+9
to15VDC, < 10mA) signals to terminals marked “Remote On / Off” on the Front Panel (16, Fig
2.1). The specied +12V signal formats are “Button Type” and “Switch Type”. These 2 signal
format options can be are programmed using the optional Remote Control EVO-RC Plus. These
options are available under programmable parameter called REMOTE SWITCH grouped under
“Select Parameter Menu Map for Group 5: OTHER FUNCTION”. Please refer to the following
Sections of the of the Manual for Remote Control EVO-RC-PLUS:
• Section 4.1.3.3, Fig 4.4: Screen No. 4 – “OTHER FUNCTION, REMOTE SWITCH”
• Section 4.8.1, T
able 4.7: Srl No. 4 “REMOTE SWITCH”
- 0=Button T
ype (Default); 1=Switch Type
• Section 4.8.2.4: Detailed explanation of programmable parameter REMOTE SWITCH
6.2.1 Button Type (Default)
This type of external +12V signal format is used when the signal is fed through an external
series connected Push Button (+12V will be fed as long as the Push Button is kept pressed).
Control logic used is as follows:
• When the EVO
TM
is in OFF condition, momentary feeding of +12V signal through the
external Push Button for > 2 sec will turn the unit ON condition. The EVO
TM
will remain
ON even when the Push Button is released
•
When the EVO
TM
is in ON condition, momentary feeding of +12V signal through the
external Push Button for > 5 sec will turn the EVO
TM
to OFF condition.
NOTE:
If the external Push Button is pressed for < 5 sec, the unit will NOT switch OFF
6.2.2 Switch Type
This type of external +12V signal format is used when the +12V signal (+9 to 15 VDC, <
10mA) is fed through an external, series connected On/Off Toggle / Rocker Switch or Relay
contact (+12V signal will be fed continuously when the switch in ON condition / Relay contact
is closed and +12V signal will be removed when the external On/Off switch is in OFF condi-
tion or the Relay contact is open). Example of this type of Remote On/Off Control signal for-
mat is the Ignition Switch in a vehicle. When the Ignition Switch is ON, 12V from the vehicle
battery will be available. When the Ignition Switch is OFF, 12V will be switched OFF. Control
logic used is as follows;
• When the exter
nal On/Off Switch is turned ON or when the Relay contact is closed,
continuous +12V control signal will be made available and the EVO
TM
will turn ON.
EVO
TM
will remain ON as long +12V control signal is available through the ON condition
of the external On/Off Switch or the closed Relay contact
• When the exter
nal On/Off Switch is turned OFF or if the Relay contact opens, the +12V
signal will be removed and the EVO
TM
will switch OFF
!
CAUTION!
When “Switch Type” of ON/OFF control described above is selected, the ON/OFF
Button on the front panel of the unit (12, Fig 2.1) should NOT be used to turn ON
or turn OFF the unit. The front panel ON/OFF Push Button will now follow the
above “Switch Type” control logic wherein the unit will remain ON only as long
as the Button is kept pressed and will turn OFF in 2 seconds after it is released.
