OPERATION

Initializing the Machine

1. On completion of the Printer/TM TCM installation turn the TM TCM Isolator to the ON

position (FIG 5). The Green lamp should illuminate indicating that the TCM is energized

and the Controller display will initially show as (FIG 6) with ‘TEST’ flashing.

FIG 5 FIG 6

2a. After approximately 5 seconds, the Controller display will change. If no output

temperature signal is available from the printer, the controller will display ‘0.0’ and

the Orange beacon segment flash quickly. The TM TCM will not start (FIG 7).

Note:

FIG 7

The printer does not output temperature signal to the TM TCM until the initialization

sequence has completed. If after 1 min a temperature signal is still not present the

Orange beacon flashes at a slower rate. After a further 1 min without signal the Amber

beacon is continuously lit. These periods are determined by the ‘Disconnect’ and

‘Shutdown’ settings on the control PCB.

2b.) When an output temperature signal is available from the printer, the top figure

(larger text) on the Controller shows the actual printer temperature (PV) in

Red/Orange/Green (depending on its proximity to the target temperature), with the target

temperature (SV) displayed on the bottom of the controller in Green (FIG 8). The TM

TCM will start and begin working to achieve the target temperature.

FIG 8

3. The target or desired operating temperature (SV) of the printer can be adjusted to

a value between 23°C and 28°C. To adjust the desired target temperature press

button . The display will change with ‘PV’ showing ‘SP’ (FIG 9)

FIG 9

The ‘▲’ and ‘▼’ keys can be used to select a target temperature value (SV)

between 23.0°C and 28.0°C (FIG 10).

FIG 10

On reaching the desired target temperature, press key . The display will return

to normal showing current printer temperature (PV) and new target temperature

(SV). (FIG 11)

4. The Process Temperature (PV) within the Printer should move towards and stabilize

within +/- 1°C of the Set Value Temperature (SV) in approximately 30 minutes (FIG12).

5. During TM TCM operation condensate will be produced by the Air Conditioning Unit

(ACU). Condensate will be collected in the Condensate Container. The beacon will

indicate the state of the Condensate Container. Failure to empty the Condensate

Container will result in automatic TCM shutdown to prevent further condensate being

produced (FIG 13).

Monitor Condensate Level Regularly to Prevent Machine Shutdown.
