Rear panel

Fig. 2. Rear panel

Mains - ON/OFF switch. When the red circle is visible the instrument is 0ff.

Mains connection - Mains power connection, fuse ‚ fuse holder and a rotary selector switch that adapts the instrument t different mains voltage (100/120/220/240±10 % VAC).

Remote - A 15-pin connector for operation of the instrument from a remote source or for control of a pump, e.g. Peristaltic Pump P-1/ MicroPerpex S.

Valve - Removable plug with screw contacts for connecting an accessory valve e.g. Valve PSV-100. Note: switch the instrument off before attempting to connect or disconnect a valve.

Event mark - Removable plug with screw contacts for connecting an event marker operated by contact closure, 0.2 sec.

Monitor - Removable plug with screw contacts for connecting a monitor giving a signal of 10, 100 or 1000 mV.

Drop counter - Socket for drop counter cable from delivery arm. Also suitable for drop counter option for FRAC- 100.

Printer A 25-pin female D-type connector (FRAC-200 only).

Short instruction

A Short lnstruction panel for day-to-day guidance in the operation of the fraction collector is mounted directly under the keyboard.

Delivery arm

The delivery arm positions the delivery tubing over tubes in the rack. A tube is located by a tube sensor which rests against the top of the tube. The pressure of the sensor against the tube operates a switch which sends a signal to the control circuit.

                                               peak and tube at peak maximum

Run evaluation                        Displays time, volume or drop number

                                               remaining in current fraction; tube number,

                                               time, volume or drop number from start;

                                               flow rate (ml, drops/min only), monitor

                                               signal (% FS) total number of peaks

                                               collected; time, volume or drop number of

                                               last power failure

Memory protection                  Programmed parameters and stored data

                                               are guaranteed for at least 1 hour after the

                                               instrument is switched off or in the event of

                                               a power failure. Under normal conditions at

                                               least 4 days storage can be expected
