CHAPTER 5 ANALOG PROGRAMMING
23
5-1-2. OUTPUT VOLTAGE ADJUSTMENT BY ANALOG PROGRAMMING
Use Programming controls port (hereinafter referred to it as ”APG”) on the rear panel to supply 0~10Vdc between
P16(+) and P26(-). The 10Vdc corresponds to full scale of output.
The analog programming voltage should not exceed 10.5Vdc. The OVP will be executed whether the
output of DC power is ON or OFF.
5-1-3. OUTPUT CURRENT ADJUSTMENT BY ANALOG PROGRAMMING
Use APG on the rear panel to supply 0~10Vdc between P18 (+) and P26 (-). The 10Vdc corresponds to full scale of
output.
The analog programming voltage should not exceed 10.5Vdc. The OCP will be executed whether the
output of DC power is ON or OFF.
5-1-4. OUTPUT ON/OFF EXTERNAL CONTROL SETTINGS
(1) Use APG on the rear panel to connect both of P21 and P25. To short or open P21 and P25 to control output
ON/OFF.(non-isolated)
(2) Before controlling ON / OFF by short/open P21/P25, it is required to set EO.C to be ON (see 8-6-14 EO.C
Control Menu), this action, hence, will be activated.
(3) Supply 5Vdc to P13-P14 to enable the output.(isolated)
Use the photo-coupler or the relay to control.
Be aware of polarity when using the photo-coupler and refer to the figure
on the right.
It is recommended to move the contacts as near the pins as possible.
5-1-5. OUTPUT EMERGENCY OFF EXTERNAL CONTROL
(1) Use APG on the rear panel to short the P23 and P25.
(2) When controlling this action, ERROR 77 will be occurred (please refer to Chapter 11), and the output is OFF.
Use the photo-coupler or the relay control.
Be aware of polarity when using the photo-coupler and refer to
the figure on the right.
It is recommended to move the contacts as near the pins as possible.
