Programming of Operating Parameters
NOTE: OV Alarm hysteresis is as follows:
(i) 0.5V for PSR-1200-24: The OV Alarm will automatically reset when the voltage drops to 0.5V
below the programmed OV setting
(ii) 1.0 V for PSR-1200-48: The OV Alarm will automatically reset when the voltage drops to 1.0V
below the programmed OV setting
10.2.2.6 “f. UV Alarm”: Sets the voltage threshold for alarm for Under Voltage (UV) on the DC input side.
If the DC input voltage falls to the programmed threshold, the following indications will be activated (The
Inverter Section will not shut down at this stage but will shut down if the voltage further drops to the
programmed threshold of “UVP Setting” (See Section 11.2.2.3):
• LCD Screen (6, Fig 6.1) will display “** Warning** Under voltage detected!!”
• LED marked “ALARM” (5, Fig 6.1) will be lighted (Orange)
• Buzzer Alarm will be activated (if “Enabled” – See Buzzer Setup at 10.2.1.5). At the same time, the
SPDT Signaling Relay will be activated (when “Enabled” – Relay Setting at Section 10.1.2.6)
Parameter

Default
f. UV Alarm
(Under Voltage Alarm)
PSR-1200-24: 17.0 to 23.0 VDC
21.5 VDC
PSR-1200-48: 34.0 to 46.0 VDC
43.0 VDC
NOTE: UV Alarm hysteresis is as follows:
(i) 0.5V for PSR-1200-24: The UV Alarm will automatically reset when the voltage rises to 0.5V above
the programmed UV setting
(ii) 1.0 V for PSR-1200-48: The UV Alarm will automatically reset when the voltage rises to 1.0V above
the programmed UV setting.
10.2.3 Main Menu for Parameter Setup Groups 1-6 > Group 3 “Output Setup” > Sub-Menu for
“Output Setup”
10.2.3.1 “a. Output V”: Sets the output voltage of the Inverter Section.
Parameter
Programmable Range
Default
a. Output V.
(Output Voltage)
100.0 to 120.0 VAC
120.0 VAC
10.2.3.2 “b. Output FREQ”: Sets the output frequency of the Inverter Section.
Parameter
Programmable Range
Default
b. Output FREQ.
(Output Frequency)
45.0 to 65.0 Hz
60.0 Hz
10.2.3.3 “c. Sync FREQ”: This parameter is used to set the “Synchronizable Frequency Window” of the
AC GRID. The Inverter will be able to synchronize the frequency and phase of its output voltage with
the frequency and phase of the AC GRID voltage only if the AC GRID frequency remains within the
“Synchronizable Frequency Window”.
