Positions 5 and 6 of SW1 and SW2 allows alarm signals to be produced from either
internal relay, Form C contacts (one NO, one NC) or open-collector logical alarm signals
(see PAR. 3.8.2).
•
MZ Models only:
Position 7 of SW1 either enables (default) or disables using the inter-
nal power supply reference voltage to power the DC ON/ALARM indicator. Position 8 of
SW2 either disables (default) or enables using the HSF output voltage to power the DC
ON indicator (see PAR. 3.4.3). Only one of these two must be enabled, the other dis-
abled.
•
Position 8 of SW1 either disables (default) or enables the visual alarm indication (see
PAR. 3.8.1).
FIGURE 4. DIP SWITCH CONFIGURATION
3.2
FRONT PANEL ACCESS.
The front panel provides a power ON/OFF switch controlling input power and a "VDC ON" indica-
tor which lights green when the unit is operating. If the unit is connected in a parallel configuration,
the indicator lights red if the unit shuts off automatically, or the POWER switch is set to OFF.
CAUTION: DO NOT repeatedly toggle the power ON/OFF switch as this may cause unit to
fault.
NOTE: The ON/OFF switch must be set to OFF before removing unit from rack adapter.
If remote on-off is not enabled (see PAR. 3.5), the OUTPUT RESET button restores output power
in the event that overcurrent or overvoltage protection has tripped, or thermal overload or fan mal-
function has occurred.
