Page 10: Putting Into Operation
Chapter 3 3.1 Putting into operation Prior to putting the instrument into operation, a threepole power cord must be connected to the power barrier strip 'TB1' on the rear panel. The gauge of the power cord is to be selected so, that the cord can carry 15A at 230V or 30A at 115V. -
Page 11: Remote Voltage Programming
When using long sensing leads, it is good practice to screen cables and to provide the blocking capacitors, as shown in Fig.4, connected to the instruments terminals. With sensing leads connected but load leads interrupted, a protection circuitry will inhibit both pre-regulator and series-regulator. - Page 12 3.5.1 Resistance voltage programming (RVP) Configuration: 1. Push the 'EXTERN' knob on the front and switch 'S1' upwards. 2. Connect the programming resistance between TB3-8 and TB3-15 Note: 1. The output voltage will be proportional to the programming resistance. For 10KOhm the output has nominal value.
- Page 13 Operation: 1. Switch on power supply 2. Switch on the programming voltage 3. The output voltage will be proportional to the programming voltage. For 10V (5V) programming voltage the output has nominal value. Note: 1. Stability, ripple and thermal-coefficient are now a function of the programming source.

Page 14: Remote Current Programming
3.6 Remote current programming 1. The output current can be adjusted by means of a remote programming resistance or a remote programming voltage. 2. When using long programming leads, use the same precautions as for remote voltage programming ( see chapter 3.5) 3.61 Resistance current programming (RCP) Configuration: 1. - Page 15 3.6.2 Voltage current programming (VVP) (V = 5V or 10V) PROG Configuration: 1. Push the 'EXTERN' knob on the front and switch 'S2' downwards. 2. Connect: Negative from the programming voltage to TB4-8. Positive from the programming voltage to TB4-6 Note: The intruments are factory-preset for 10V programming.

Page 16: Series Operation
3.7 Series operation 3.7.1 Series operation by simply connecting the output terminals Series operation of ATLAS power supplies enable a higher output voltage, however the total output voltage should not exceed 300V. Besides it is to be noted that a voltage drop due to the connecting lines is generated according to the current load. - Page 17 The output voltages are adjusted via the corresponding VOLTAGE- potentiometer. The total output voltage is the sum of the two adjusted voltages. The two units may be programmed in different manner (e.g. unit 1 in RVP, unit 2 in VVP). If the current-limits are not equal, the lower current-limit will be efficient.

The master can limit only the current through +R load. The current limit from slave can be set with a resistance (<...

3.8 Parallel operation If higher output currents are required, it is possible to have the ATLAS power supplies operate in a parallel manner. 3.8.1 Simple output load terminals connection In order to get an even load current distribution, both ATLAS power supplies have to be adjusted to the same output voltage prior to connecting the output load terminals. - Page 20 Remove jumper “J304” on the Regulation board (see last page) Fig. 11 Atlas 1200 Page 20 von 26 ISSUE 07/05...

Page 21: Overvoltage Protection
3.9 Overvoltage protection 3.9.1 Internal programming of the overvoltage-threshold Adjusting the threshold: 1. Turn, by means of a small srewdriver, the 'OV-ADJ' potentiometer full clockwise. 2. Turn on the unit and adjust the output voltage on the value of the desired threshold. Should this value be higher then the nominal voltage, use a short-protected, floating external DC-supply with sufficient voltage and connect it directly on the output load terminals. - Page 22 S1 and S2 with no meaning 0..12V 0...12kOhm 100Ohm (see note) Fig. 12 Note: The remote-programmed threshold and the one adjusted by means of the 'OV-ADJ' potentiometer, are members in a minimum function, it acts always the smaller valule. In this minimum function automatically will be considererd the threshold programmed via the Opt.34- board (Interface-card) too, if the Opt.34-board is activated.
- Page 23 3.9.3 Delayed current limiting. The load can draw from the power supplies ATLAS an overcurrent (150% from the actual current limit, I ) for a period not exceeding 500ms. After the delay-time, the current will be limited to the currrent limit. Every overcurrent period is followed by a relaxtion-time, approx. 10 times longer than the overcurrent-time, in which no overcurrent can be delivered (see diagram in fig.

Page 24: Monitor Output
3.10 Monitor and status outputs 3.10.1 Monitor outputs The output voltage and current can be read via two analog signals. These signals are proportional with the output parameters and are rated to +10V. They are marked 'V-Monitor ' (TB4-7) and 'I-Monitor ' (TB4-13), and measured against TB4-14. Both monitor outputs may be loaded with max. - Page 25 CHAPTER 4 (Options) 4.1 Option 07: 115 VAC line connection (see Fig. 14) 1. Option 07 power supplies are delivered for 115 VAC line voltage. 2. Switching from 115 VAC to 230 VAC a) Remove the links connecting terminals 1-21 and 2-22 on the power transformator T101. Connect the jumper J3 on transformer T101 between terminal 21-22.
