About VR+ / VR-, please consider that this two terminals act as two
options:
 External Local/Remote: This mode has been used for external
24V+ to VR+ and 0V to VR- pin terminal to operate and energize
DO relays externally controlled. In this mode the jumper strap of
J1 and J2 must be in position of 2-3.
 Indication Local/Remote: This mode has been used to indication
of Local/Remote Switch in front of power supply. In this case VR+
act as positive wet digital indication and VR- for 0V of common
indication, when L/R switch of PS card be in position of "R"
