It is easy to connect a THC to A Burny 2.8
The 3TB treminal strip (in the rear of the cabinet) is where you connect the THC (any type)
The Plasma Start Contacts are 15 & 16
The Height Freeze Contacts are 19 & 20 N.O. and 19 &18 N.C.
Cut Sense Input is 1 and for a 24 Volt Signal 2
120 Volt Signal 3
220 Volt Signal 4
You remove your plasma interface, connect the THC to the 3TB termionals and connect your plasma to the HTC per the mfg instructions.
Be careful with the Hypertherm THC's.
Their Cut Sense outputs are only rated for 24 Volts DC at 15 ma. You can destroy them easily. Most other brands use a relay contact output.
The Burny 2.8 input requires you supply 24VDC if using a Hypertherm THC for cut sense.
Most others with a relay output you can use any voltage (AC or DC) available.
I have attached a few pages I scanned from a Burny 2.8 Plus manual. That is the newer version, but the interface is the same.
You can request the manual from
www.burny.com, or call Tech Support in Cleveland and they may have a copy of the 2.8 manual available as a .pdf.
