[. . . ] This button can be pressed at any time and has no effect on the temperature regulation functions of the controller. Display Lights indicate the source of the value displayed on the numeric display. Setpoint is adjusted by a potentiometer accessible with the 2. 5mm screwdriver provided. To adjust the setpoint make sure the numeric display is set to Setpoint, and then adjusts the setpoint potentiometer to the desired value. [. . . ] This is insurance that the controllers learning curve did not wonder during the few seconds it takes to insert a dish. When the alarm goes off and the red LED lights next to the Reset button. Calibrate substitutes precision resistors into the circuit that reads the thermistor so that calibration adjustments can be made to a known value. Stage is a six pin mini DIN connector where the heated slide carrier is plugged in. Back Panel of the Delta T4 Controller Figure 2 AC Power line input, power switch, voltage selector, and fuses are all incorporated in the AC Power Input Module. The controller can operate between 90 - 260V 50-60Hz, or a 24V battery can be used as an alternate power supply. The fuses can be accessed by prying the fuse block out of its socket with a small screwdriver wedged under the small slot in the opening of the AC line receptacle. When replacing the fuse block, make sure to align the arrow on the outside of the fuse block with the closest voltage value to your supply line voltage: · For 90-130-supply line voltage place the fuse block with the arrow pointing to 110-120V. · For 180-260 supply line voltage place the fuse block with the arrow pointing to 220-240V. Heated Lid Adjustment is the adjustment for the voltage sent to the Heated Lid. This voltage should be measured at the Heated Lid with an external meter. Temp Out is a voltage output direct from two instrument amplifiers reading the thermistor from channel A and B. Left pin is channel A, center pin is channel B, and right pin is ground. Remote Setpoint is an analog input that allows the user to set the controllers setpoint from an external DC source. A DC voltage can be applied to the tip of this jack equal to temperature /10. When the jack is inserted into the controller it will automatically switch to the jacks value. When removed it will default to the setting on the front of the controller. Fixing Adjustment allows the user to adjust the voltage sent to the heated slide carrier when the Fixing Switch is depressed. Fixing Switch is provided so that cells can be fixed on the stage of the microscope. This switch should only be used when you intentionally want to overheat your cells. TTL is a BNC connection used to change the mode of operation of the controller from a remote source such as an image acquisition computer or slave from a shutter trigger. To change to Imaging mode, apply a TTL logic high and hold to this BNC. The controller will remain in Imaging mode as long as the TTL condition remains high as indicated by the LED on the front panel. 3560 Beck Road · Butler, PA 16002 · Voice: 724-282-7145 · Fax: 724-282-0745 · E-mail: info@bioptechs. com · Web: www. bioptechs. com Instructions: 1. [. . . ] The sensitivity of the controller, 0. 1°C, coupled with the speed and intensity of the controller's response, may cause the slide carrier to flex a detectable amount during narrow depth of field imaging. The controller is equipped with a circuit that bypasses the dynamic temperature control mode and permits you to temporarily send a constant DC current to the slide carrier to eliminate the possibility of an abrupt change of energy from occurring as might happen in dynamic mode. The controller can be switched from its default Dynamic control mode to Imaging mode by several means: 1. TTL communication from an external trigger such as a acquisition host or slave from a TTL shutter trigger Operate the Delta T4 in the auto (dynamic) mode when you are not scanning or acquiring images.
