DIP SWITCH CONFIGURATION
The HSF 300W Series incorporates two DIP switches, SW1 and SW2 (see Figure 4), which must
be configured before the unit is installed in the rack adapter. The DIP switches control the follow-
ing parameters:
•
Positions 1, and 2 allow the output to be controlled either by the front panel Vadj control
(see PAR. 3.4.1) or by remote control using either an external trimpot or voltage source
(see PAR. 3.4.2). These positions can also be configured to allow a master/slave combi-
nation to be controlled either by the front panel Vadj control or by remote control using
either an external trimpot or voltage source (see PAR 3.4).
•
Positions 3 and 4 either allow the front panel reset button to be used to reset the unit
after a fault or allow Remote on-off via mechanical switch or logic level (see PAR. 3.5).
•
Positions 5 and 6 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. 3.7.2).
