The 'Bulk Supply' Panel is shown in screen shot 8 below. This panel is used for enabling/disabling an
external bulk supply only. The bulk supply must support being remotely enabled/disabled, which is
accomplished by the crate via the 'Crate OK' connection on the back of the crate. This connection is a
BNC connector (J2) which is a dry contact (relay) output. When enabled ('PS On/Off' box checked) a
short is placed across the enable connection of the power supply pins to turn the output of the bulk
supply on. The user must consult the manual of the specific power supply in use to determine the
connections necessary for this function. BiRa Systems can help with this if necessary.
It is necessary to configure the bulk supply properly to ensure that the supply comes up in the correct
state so that the output of the supply does not come on until commanded. The bulk supply voltage,
Over Current, Over Voltage protection must be set up locally and cannot be controlled by the EMCOR
module. The power supply should be set up so that when powered on the output is enabled but the
output is not on. Note that it is not necessary to remotely access the bulk supply output. The bulk
supply may be used manually by the user if desired.
