4.09 Sequence of Operation

Ultracut with DFC 3000 using TSC 3000

The purpose of this section is to explain the steps an operator should follow when using the DFC 3000 with the

TSC 3000 touch screen control panel for a specific cutting process. Also included are steps to follow for changing

torch consumables.

NOTE

For units not using the TSC 3000 where control is embedded into the cutting table controller most of this

sequence still applies except for the parts that are specific to the TSC 3000. For those sections refer to

the cutting table controller documentation.

NOTE

When the TSC 3000 is installed, J14 on the CCM must be set for 2 Wire communication. For units not

using a TSC 3000, determine if the communication requires 2 wire or 4 wire communication and set ac-

cordingly. The XT iCNC controller requires 4 wire setting. See section 3.15 and the Appendix.

This assumes the system setup; language and units, lead lengths, etc., have already been performed by the installer

and the system is confirmed as operational.

1. Before Applying power:

a) Ensure that the required gasses are connected to the DMC 3000 inlet and gasses are turned on and set

for required inlet pressure.

b) Ensure you have a torch cartridge with consumables installed on the torch.

If you don’t know what consumables you need to use and need to select the cutting process in order to read the

consumables list on the TSC 3000, you can start up with Plasma Disabled. In this case the operation sequence

will skip to step 3.

c) Set Plasma Enable SW on the TSC 3000 to Enabled.

2. Turn on 3 phase power at the main disconnect (Plasma Enable on TSC 3000 on). Turn ON/OFF switch to the

ON position (up). System will then go through the start up sequence.

a) For about 10 seconds the decimal points of the 4 digit display blink from right to left.

b) Next the 4 rectangular LED indicators and the 4 status display digits illuminate all segments as a test.

c) Then for about 6 seconds the display shows the letter “C” (code) followed by the CCM code version.

Example “C1.2.0” . During this time various input voltage tests are being performed. If a fault is found

its code is displayed and the start up sequence halts. Faults will show “E” or “L”. If Plasma hasn’t been

Enabled by this point, E101 will be displayed. If disabled the pump will not start, the gas LED doesn’t

blink and the contactors don’t close (steps d & e). However the events of steps f & g will continue and

you can select and load the cutting process. Until the process is loaded, the display shows “0” indicating

no process has been loaded. If a fault exists the display alternates between “0” and the fault code.

d) The coolant pump starts and the Gas indicator blinks, and the display shows E304, while the cutting

gasses are purged. Purge time varies with the torch lead length and the cutting process. See section 4.04

for setting lead length. When the gas purge ends the E304 goes away but the gas LED may continue

blinking if the coolant flow hasn’t been satisfied.

e) Once coolant flow is detected, usually within 5 seconds after the pump starts, the input contactor(s) W1

(W2) close and the AC indicator lights.

f) At the same time the DMC & DPC, both Green & Red LEDs, also blink their firmware version.
