Installing CH350/L CCD

Camera Head

Caution: Opening your Series 300 camera head voids the camera warranty.

This liquid-cooled camera head uses liquid circulation to draw heat away from the thermoelectric cooler.

Ports

Install the camera head cable as follows:

1. With the CEU powered off, plug the cable end labeled CONNECT TO

CEU into the camera port on the back panel of the CEU.

2. Remove the shorting plug from the camera port on the camera head and save it. (Always re-insert the shorting plug into this camera port when the camera head cable is disconnected. The plug prevents static electricity damage to the CCD.)

3. Plug the cable end labeled CONNECT TO CAMERA HEAD into the camera port on the camera head.

Caution: This camera head must be used with a liquid circulation unit (LCU). To install

the LCU, see Connecting the Liquid Circulation Unit on page 9. Never operate the

camera without the LCU connected and operating properly.

The SERIAL REGISTER arrow on the camera head indicates the location of the serial register for the output node of the CCD. The position of the register varies, depending on the type of CCD.

Connecting the Liquid

Circulation Unit

The liquid-cooled camera must always be operated with the LCU or another acceptable liquid circulator. (To install a different liquid circulator, remove the two quick disconnects on the rear of the camera head if necessary and replace them with male 1/8” NPT fittings that connect to your liquid circulating system.

Contact Roper Scientific Customer Service for further assistance.)

In order to operate properly, the reservoir in the LCU must be at least 3/4 full:

• If you are installing a newly shipped LCU, the reservoir is filled with the proper amount of coolant. Follow connection instructions below.

• If you are not installing a newly shipped LCU, see Refilling the Reservoir

on page 19 in order to check the coolant level in the reservoir before

connecting the LCU to the liquid-cooled camera head.

To connect the LCU:

With the power switch in the off position (0), connect the LCU hoses:

Liquid Cooling Port on CH350/L Camera

1. On the camera head, press the release tab on the liquid cooling port.

2. Holding the release tab down, insert the connector on the LCU hose into the liquid cooling port.

3. Release the release tab.

When both hoses are attached, connect the power cord to the LCU (and later to an electrical outlet).

Caution: Do not allow the reservoir to drain below half full. To keep the pump primed, always operate the LCU in the upright position.

When disconnecting the LCU from the camera, it is important to keep any coolant from spilling into the camera. Make sure to see Disconnecting the Coolant

Connectors on page 19 for instructions on disconnecting the LCU.

Frequently asked questions

Store the Series 300 camera system and the LCU in their original containers. To protect the system from excessive heat, cold, and moisture, store at an ambient temperature between -20°C and 50°C with a relative humidity of 0%–90% noncondensing.

The camera system’s ambient operating temperature is 0°C to 40°C with a relative humidity of 0%–80% noncondensing.

The charge-coupled device (CCD) and other system electronics are extremely sensitive to electrostatic discharge (ESD) and the optional liquid circulation unit requires periodic maintenance. To avoid permanently damaging the system, please observe the following precautions: * If you are using high-voltage equipment (such as an arc lamp) with your camera system, be sure to turn the camera power on last and power the camera off first. * If you have a liquid-cooled camera head, you MUST operate the LCU whenever the camera is on. * Use caution when triggering high-current switching devices (such as an arc lamp) near your system. The CCD can be permanently damaged by transient voltage spikes. If electrically noisy devices are present, an isolated, conditioned power line or dedicated isolation transformer is highly recommended. * Never connect or disconnect any cable while the camera system is powered on. An unconnected cable segment can become electrically charged and can damage the CCD if reconnected. * Always install the shorting plug on the camera head when the head is disconnected from its cable. * Do not connect the camera head cable to the camera head until the cable is first connected to the camera electronics unit (CEU). * Do not disconnect the camera head cable from the CEU until the cable is first disconnected from the camera head. * The system has been configured for 100V, 110V, 220V, or 240V AC input at 50/60 Hz. Do not connect your Series 300 system to a power source for which it was not configured or to a power source that has less than 1 kVA capacity. * Never impede airflow through the equipment by obstructing the air vents. Allow at least one inch air space around any vent. * Do not “mix and match” camera heads and CEUs. Refer to the Certificate of Performance supplied with your system for the serial numbers of the camera head and the electronics unit for this system.

Clean exterior surfaces of the camera system with a dry, lint-free cloth. To remove stains, contact Roper Scientific Customer Service.
