Program Storage

Storage for 15 sets of tables (gradient, program event, and detector), with a maximum of 15 steps per table.

Storage for a time-based multi-method program with up to 48 individual steps.

EEPROM stores setup parameters and tables, and preserves memory indefinitely following power loss or extended shutdown.

Gradient Profiles

Eleven gradient curves (including linear, Step [2], concave [4], and convex [4]). Up to 80 curve segments can be linked.

Liquid Crystal Display (LCD)

5-inch (12.7 cm) diagonal screen.

Sixteen lines with 40 characters per line.

320 x 200 pixels.

Displays current operating conditions.

Allows operator to monitor complete gradient and timed-event tables an single screens.

Reverse video cursor prompts operator through program

setup.

Keypad, Function Keys, and Screen Keys

Dedicated keys provide direct access to all display screens.

Cursor movement keys simplify programming, editing, and parameter entering. All keys are eluent-resistant.

Programmable Timed Events

You can program and store 15 timed events for each table.

Contact closure switches S1 through S4 are located an the 600S controller rear panel for timed output to external devices.

The following actions may also be controlled by timed events:

•     Audible alarm

•     Sparge rate

•     Column temperature

•     Proceed to initial conditions of specifed table

•     Start run of specified table

•     Turn detector lamp off

Power Requirements

Maximum power: 250 VA

Frequency

47 to 63 Hz

Time- or Operator-Controllable Switch Closures

Four controllable switch cosures to ground as follows:

• TTL-compatible terminals pulled up with 10-K ohm resistors to 5 V. May be pulled up to 12 V.

• Maximum allowable current = 1.0 A.

• Maximum allowable voltage = 12 V. Outputs may be controlled directly from keyboard or from events program.

• Two modes available from keyboard and Program Events screen:

   ON = switch closed to ground.

   OFF = switch open, +5 V to ground.

• Additional mode available from Program Events screen:

   Pulse = single contact closure to ground for 600 msec.

Auxiliary Power Supply

12 V to ground fused supply. 1 A max current.

Hold Output

One TTL-compatible switch closure to ground. Maximum current sink:

100 mA. Low output indicates pumps stopped due to:

•     Exceeding high-pressure limit

•     Below low-pressure limit

•     Abort input

•     "Powerup" condition

Used to communicate with Hold input on Waters 717plus autosamplers or other compatible input to prevent further injections.

Chart Output

Two terminals (+,-) providing a 0 to 10 mV signal.This signal can be used to indicate the composition percentage of any one of the four eluents (%A, %B, %C, %D), the eluent flow rate (Flow), or the column temperature (Temp).

Pressure Output

Two terminals (+,-) for recording pump pressure traces. 10 mV/6000 psi analog output; bypasses microprocessor.

Inject

Receives a signal from an external injector (autosampler or manual injector) to initiate the chromatographic run. The Inject terminal also provides a signal to start a Waters 745B/746 Data Module (integrator).

The Inject terminal accepts signals from several outputs, including TTL signals, open collector outputs, and contact closures.

Ground Terminals

Connected to signal ground and used as reference for one of the following:

•     Outputs (Hold, Inject and switches S1 to S4)

•     Inputs (Inject and Abort) or

•     12 V power supply (not for use with 10 mV outputs)
