PSI 9000 DT Series
3.4.3.1 Menu “General Settings”
Setting Description
Allow remote control Selection “ No ” means that the device can’t be remotely controlled over either the
digital or analog interfaces. If remote control isn’t allowed, the status will be shown
as “ Local ” in the status area on the main display. See also section
1.9.5.1
Analog interface range Selects the voltage range for the analog set values, actual output values and refer-
ence voltage output.
•
0...5 V = Range is 0...100% set /actual values, reference voltage 5 V
•
0...10 V
= Range is 0...100% set /actual values, reference voltage 10 V

„3.5.4. Remote control via the analog interface (AI)“
Analog interface Rem-SB
Selects how the input pin REM-SB of the analog interface shall be working regard-
ing levels (see „3.5.4.4. Analog interface specification“ ) and logic:
• Normal = Levels and function as described in the table in
3.5.4.4
•
Inverted = Levels and function will be inverted
Also see
„3.5.4.7. Application examples“
Analog Rem-SB action Selects the action on the DC output that is initiated when changing the level of
analog input REM-SB:
•
DC OFF = the pin can only be used to switch the DC output off
• DC ON/OFF = the pin can be used to switch the DC output off and on again, if it
has been switched on before at least from a different control location
Analog interface pin 6 Pin 6 of the analog interface (see section
3.5.4.4
) is by default assigned to only signal
the device alarms OT and PF. This parameter allows to also enable signalling only
one of both (3 possible combinations):
Alarm OT = Enable/disable signalling of alarm OT on pin 6
Alarm PF = Enable/disable signalling of alarm PF on pin 6
Analog interface pin 14
Pin 14 of the analog interface (see section 3.5.4.4 ) is by default assigned to only
signal the device alarm OVP. This parameter allows to also enable signalling further
device alarms (7 possible combinations):
Alarm OVP = Enable/disable signalling of alarm OVP on pin 14
Alarm OCP = Enable/disable signalling of alarm OCP on pin 14
Alarm OPP = Enable/disable signalling of alarm OPP on pin 14
Analog interface pin 15 Pin 15 of the analog interface (see section
3.5.4.4
) is by default assigned to only
signal the regulation mode CV. This parameter allows to enable signalling a different
device status (2 options):
Regulation mode = Enable/disable signalling of CV reg mode on pin 15
DC status
= Enable/disable signalling of DC output status on pin 15
DC output after OT alarm Determines how the DC power stages shall react after an overtemperature (OT)
alarm has occurred and the power stages have cooled down again:
•
OFF
= DC power stage(s) will be off
• AUTO = The device will automatically restore the situation before the OT alarm,
which usually means the DC power stage(s) to be on
DC output after power ON
Determines the condition of the DC output after power-up.
• OFF = DC output is always off after switching on the device.
•
Restore = DC output condition will be restored to the condition prior to switch off.
DC output after PF alarm Determines how the DC output shall react after a power fail (PF) alarm has oc-
curred:
•
OFF = DC output will be switched off and remain until user action
•
AUTO = DC output will switch on again after the PF alarm cause is gone and if
it was switched on before the alarm occurred
