SECTION 6 | Operation, Protections and Troubleshooting
“Button Type” or “Switch Type”. These 2 signal format options can be programmed using the optional Remote Control
EVO-RC-PLUS. These options are available under programmable parameter called "REMOTE SWITCH". Please refer to
the following Sections of the EVO-RC-PLUS Remote Control Manual:
• Section 4.1.3.3, Fig 4.4: Screen No. 4
• Section 4.8.1, Table 4.5: Srl No. 4 “REMOTE SWITCH”
– 0=Button Type (Default); 1=Switch Type
• Section 4.8.2.4: Detailed explanation of programmable parameter REMOTE SWITCH
6.2.1 Button Type On/Off Control Using +12V Signal (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. The EVO™ 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
OFF.
NOTE: If the external Push Button is pressed for < 5 sec, the unit will NOT switch OFF
6.2.2 Switch Type On/Off Control Using +12V Signal
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 condition or the Relay contact is open). Example of this type of Remote On/Off Control signal format 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 external 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 external 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 at Section 6.2.2 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.
