6.2 Powering on / off by feeDing eXternAl +12v control
SignAl to terminAlS mArKeD "remote on/off" on the
front PAnel (15, fig 2.1)
Programming option is available through the Parameter Setting Menu (Parameter is called
"rEMOTE SWITCh") of the optional remote Control Model No. EVO-rC (Please see Section
4.8 of Appendix A) for 2 types of external +12V control signal fed through remote ON/Off
Terminal (15, fig 2.1). Details of these options are given below:
6.2.1 button type (Default)
This type of logic is applicable when the +12V Control Signal is fed through a series
connected Push button contact. Control logic used is as follows:
• When the unit is in Off condition, a momentary contact of the Push button > 2
seconds will turn the unit ON.
• When the unit is in ON condition, pressing of the Push button < 5 seconds will have no
effect and the unit will continue to remain in ON condition.
• When the unit is in ON condition, pressing the Push button > 5 seconds will turn the
unit Off.
6.2.2 Switch type
This type of logic is applicable when the +12V Control Signal is fed through a series
connected external manual Switch or through an external relay contact. Logic used is as
follows:
• When the unit is in Off condition, toggling the external manual switch to ON position or
closing the external relay contact will immediately turn the unit ON.
• When the unit is in ON condition, toggling the external manual switch to Off position
for 2 seconds or opening the relay contact for 2 sec will turn the unit 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.
6.3 oPerAtionAl informAtion through leDS AnD buZZer
Table 6.1 shows the operational states of the unit indicated by the following LEDs on the
front panel of the unit and buzzer:
o green leD marked "on" (12, fig 2.1)
o red leD marked "fault" (13, fig 2.1)
Optional remote Control Model EVO-rC (see Appendix A) will be required for more detailed
messaging that is available through its LCD display and LEDs. This remote will also be required
for programming of various parameters to suit specific requirements.
