Move the lock switch into the upper position to lock out all changes from the front panel, including
set point assignments and values as well as the Mini BA sensitivity adjustment.
2.1.10
Power down MC300 and connect peripherals
Once you’ve confirmed that the MC300 is functional, power it down. Connect all sensors using sensor
cables, and connect any analog output, or set point cables as necessary. Be sure to follow all safety
precautions associated with these items and your system.
2.1.11
Restart MC300
Restart your MC300. It should be ready for use. Contact the Fredericks Company with any comments
or questions.

Supply Voltage
110 VAC
±
10% or 220 VAC
±
10%
Supply Current
.3A at 115 VAC, .15A at 230 VAC
Maximum Power
35 W
Power Connection

2.3.2
Supply Voltage
The MC300 can be configured to operate with either a 110 VAC
±
10% or 220 VAC
±
10% supply. The
configuration can only be set at the factory. The default setting is 110 VAC compatibility and 220 VAC
operation must be specified upon order. Changing the configuration requires the user to return the
unit to Fredericks Company.
2.3.3
Electrostatic Discharge Sensitivity
The MC300 contains ESD-sensitive components but is designed to withstand
±
2 kV discharges using
the human body model.
2.4
Set Points
There are four set point relays available for use to control ON/OFF or open/close (binary state) devices.
The relays are assignable to any one of the vacuum signal input channels through front panel software
control. When the pressure is lower than the ON value of the set point, the NO and C terminals are
connected (normally open and common). When the pressure is higher than the OFF value of the
set point, the NC and C terminals are connected (normally closed and common). When the unit is
powered down, the NC and C terminals remain connected. The relays are single pole double throw
(SPDT) and rated for 6 A at 24 V DC or 10 A at 120 V AC.
