temperature readout and from the current program step shown on the Lower
display.
After the completion of the cycle, and after a sufficient cool-down, turn off the
Control Power Switch. The control system will shutdown and all indicator
lamps will extinguish. This completes the functional checkout.
3.4 Machine Operations
Daily operation of the machine requires that a routine be developed that assures
long life for the machine and guards against premature failures. When a routine
is adhered to, machine problems or failures will be immediately recognized.
3.4.1 Start-up Procedure
1. Turn on the Control Power. The ¼ DIN Ramping Controller will boot up
and the Main Page will appear. Wait a minimum of 30 seconds after the
control power has been shut off before turning it on again; this allows the
¼ DIN Ramping Controller to fully reset.
2. Turn on the supply gas at the source and adjust the input regulators as
necessary. If the machine will be used with formic acid, please refer back
to paragraph 3.3.1, and to Addendum 1 in Section 7 of this manual.
3. If the machine is equipped with the optional CW-5 cooling system, turn it
on.
4. If the machine is equipped with the optional VP-5 vane pump or DP-5 dry
pump, turn it on.
5. Open the lid: Press the Lid Cycle Switch and wait for the
Exhaust/Vacuum Cycle to finish; pull the handle back and move it to the
UP position. Press the Lid Cycle Switch a second time and wait for the
Backfill Cycle to finish; move the lid to the open position.
6. Install the tool: Align the tool with the metal tabs on the radiation shield;
gently lower the tool until it touches the tabs.
7. Insert the thermocouple.
8. Close the lid: Lower the lid to the closed position and continue pushing
on the handle until it stops in the DOWN position. Press the Lid Cycle
Switch and wait for the Vacuum Cycle to finish, verify that the locks have
engaged.
3.4.2 Automatic Cycle Operation
1. Pressing the Start Cycle Switch runs the last profile; it is not necessary to
re-select the program.
2. Pressing the Stop Cycle Switch interrupts the program at any time. The
Main Page will appear and the process is immediately stopped.
3.4.3 Shutdown Procedure
1. Close the lid.
2. Turn off the Control Power Switch.
