Installation

Fit the supplied air return duct to the printer using the appropriate photograph below. Fit

the filter to the duct (where applicable).

Air Return Duct A

Air Return Duct B

Position the TCM adjacent to the printer, allowing sufficient access to the condensate

container, with consideration given to TCM and Printer access covers. Connect the TCM

flexible ducting to the relevant printer port.

Note:

Hose lengths may be reduced as required to improve the look of the installation and

help improve airflow and cooling performance.

OPERATION

Initializing the Machine

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

(FIG 10). The Green lamp should illuminate indicating that the TCM is energized and the

Controller display will initially show as (FIG 11) with ‘tESt’ flashing.

FIG 10 FIG 11

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

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

and the Orange beacon segment flash quickly. The TCM will not start (FIG 12).

FIG 12

Note:

The printer does not output temperature signal to the 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 Controller

shows the actual printer temperature (PV) in Red, with the target temperature

(SV) displayed in Green (FIG 13). The TCM will start and begin working to

achieve the target temperature.

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

a value between 19°C and 30°C. To adjust the desired target temperature press

button ‘P’. The display will change with ‘PV’ showing ‘SP 1’ (FIG 14)

FIG 14

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

between 19.0°C and 30.0°C.

FIG 15

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

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

(SV). (FIG 16)
