Switched AC Outlet Fuses Both of the switched outlets on the back of the TDC5 have fuses above and to the left of the outputs. In accordance with international safety standards, both the line and neutral connections are fused. For Output 1, the maximum allowed fuse rating is 3 A;... -
Page 11: Heater Safety
The switched electrical outlets on the TDC5 rear panel must always be treated as on whenever the TDC5 is powered. Remove the TDC5 line cord if you must work with a wire in contact with these outlets. Do not trust that the control signals for these outlets, when off, remains off. Do not touch any wire connected to these outlets unless the TDC5 line cord has been disconnected. - Page 12 Chapter 1: Safety Considerations If the problem is AC power-line transients (often from large electrical motors near the TDC5): Try plugging your TDC5 into a different AC-power branch circuit. Plug your TDC5 into a power-line surge suppressor. Inexpensive surge suppressors are now generally available because of their use with computer equipment.

Initial Visual Inspection After you remove your TDC5 from its shipping carton, check it for any signs of shipping damage. If any damage is noted, please notify Gamry Instruments, Inc. and the shipping carrier immediately. Save the shipping container for possible inspection by the carrier. -

Flexcell’s heating coil. AC Line Connection The TDC5 is designed to operate at AC line voltages between 90 and 240 VAC, 50 or 60 Hz. You must use a suitable AC power cord to connect the TDC5 to your AC power source (mains). -
Page 15: Power-Up Check
Make sure that a newly installed TDC5 has no connection to its switched OUTPUT outlets when it is first powered. You want to verify that the TDC5 powers up correctly before you add the complexity of external devices. -

USB connector.) Using Device Manager to Install TDC5 1. After the TDC5 is plugged into an available USB port on the host computer, turn on the host computer. 2. Log into your user account. 3. Run Device Manager on the host computer. - Page 17 Select a number of 8 or less. You do not need to change any other settings. After you have made a selection, remember this number to use during the Gamry Software Installation. 11. Click the OK buttons on the two open dialog boxes to close them.

Page 18: Connecting The Tdc5 To A Heater Or Cooler
Even cracked insulation can be a hazard when salt water is spilled on a wire. The AC power for the heater is drawn from Output 1 on the rear panel of the TDC5. This output is a IEC Type B female connector (common in the USA and Canada). -
Page 19: Connecting The Tdc5 To An Rtd Probe
Connecting the TDC5 to an RTD Probe The TDC5 must be able to measure the temperature before it can control it. The TDC5 uses a platinum RTD to measure the cell temperature. A suitable RTD is supplied with the TDC5. This sensor plugs into adapter cable supplied with your TDC5: Contact Gamry Instruments, Inc. -

Page 21: Chapter 3: Use
Thermal Design of Your Experiment The TDC5 is used to control the temperature of a electrochemical cell. It does so by turning on and off a heat source that transfers heat to the cell. Optionally, a cooler can be used to remove heat from the cell. In either case, the TDC5 switches AC power to the heater or cooler to control the direction of any transfer of heat. -
Page 22: Tuning The Tdc5 Temperature Controller: Overview
The temperature controller in the TDC5 can be used in an ON/OFF mode or a PID (Proportional, Integral, Derivative) mode. The ON/OFF mode uses hysteresis parameters to control its switching. The PID mode uses tuning parameters. -
