2. Installing

2.1 Unpacking and Inspection

Inspect the shipping container for external damage. After unpacking inspect the instrument for any shipping damage. If visible damage exists, a claim should be filled with the carrier. If anything is missing from your order contact JC CONTROLS.

Included with each JC Controls TC610 is :

1 TC610 Controller

2.2 Thermocouple Tube Installation

Situate the gauge tube in a clean, dry vacuum system. Ideally the open end should point down so as to be self-draining should any vapors condense in it. Thread metal tubes into 1/8" female NPT threads. For best accuracy, allow the tube to outgas in the vacuum system for approximately 24 hours before operating with the vacuum gauge.

2.3 Final Installation

Put the instrument on a stable surface. Install the 3 prong power cord to a 115 VAC single phase outlet. Plug the TC cable into the TC tube and the unit. If the process control set points are to be used, the connections to the relays are through the six pin DIN connector on the back of the unit. If a recorder is to be used, connect it to the 3/32" submini phone jack on the rear.

2.4 Tube Selection

The TC610 is configured to run the acompaning tube shipped with the gauge. If the TC-610 is shipped without a TC tube, the gauge will be setup for use with a DV-6M TC tube. For instructions on changing the tube type please contact the factory. Tollfree 1-877-837-6677

3. Operation

3.1 Vacuum Reading

With a tube connected to the unit, the display will show the vacuum in the tube. If the tube is a DV-6M, the vacuum reading will be in microns ( 1/1000 torr). If the tube is a DV-4D, the reading will be in torr.
The DV-6M tube reads vacuum from 1 to 1000 micron. Its most accurate range is from 10 to 200 microns. The TC610 will display 1000 if the tube is anywhere between 1000 microns and atmosphere.
The DV-4D tube reads vacuum from 0.01 to 20 torr. Its most accurate range is from 0.2 to 5 torr. The TC610 will display 760 when the pressure is between 21 and 760 torr.

3.2 Setpoint Setup and Operation

The TC610 has two process control setpoints. Each one is connected to a SPDT 3A relay. The value of the setpoint is dependent on which tube is being used, but the full range of both tubes can be used. To adjust SP1 press the [SELECT] key once, the display will show the current value of SP1. To adjust the value press the [+] or [-] keys. Press the [SELECT] key once to adjust SP2 or twice to get back to the vacuum mode. The setpoint relay will switch when the vacuum is above or below the setpoint value.

The six pin DIN socket on the back panel accesses the setpoint relays.

The following is the pinout:

3.3 Recorder output

The recorder output will monitor the vacuum at the TC tube and give an output of 0 - 3 VDC that is log / linear. Below is a table that will give you an example of different voltages verses pressure.

Voltage DV-4D DV-6M
0.1 0.01 torr 1.0 microns
0.7 0.07 torr 7.0 microns
1.1 0.10 torr 10 microns
1.5 0.50 torr 50 microns
2.1 1.0 torr 100 microns
2.3 3.0 torr 300 microns
3.0 10.0 - 760 torr 1000 microns

The recorder output is accessible through the 2.5mm jack on the back of the unit.
