Setting section | |
Setting method | ・ Keyboard operation (membrane switch with a key click buzzer) ・ External setting is available by installing a setting point option or RS-232C option |
---|---|
Setting value storage | ・ Initial set values: NOV RAM (Non-volatile RAM) ・ Other set values: C-MOS RAM with backup of a lithium battery (Effective for more than 7 years depending on usage conditions and storage environment.) |
Setting value protection | Setting operation can be locked to prevent unauthorized modifications of default values and calibration by malfunction |

I/O section | |
External output signal | Transistor’s open collector output (Emitter = COM terminal); Output is LO when transistor is ON (Near zero, SP1, SP2, SP3, go or comp, over, under, high limit, Low limit, stable, weight alarm or error, run) |
---|---|
External input signal | ON when shorted to COM terminal by TTL-level relay, switch, transistor, or open collector output. (Feed / discharge, tare ON, tare OFF, zero, gross / net, hold or judgment, start, stop) (Drive current: 10 mA or less) |
Output Conditions | – SP1: Net weight >= final weight-SP1 – SP2: Net weight >= final weight-before final – SP3: Net weight >= final weight-FF – Under: Net weight < final weight-underweight – Over: Net weight > final weight-overweight – Go: Final weight+overweight >= netweight >= final weight-underweight |
Interface | ・ SIF: 2-wire type serial interface (standard); Interface to link with Unipulse printer or external display. ・ SPI: Interface for set-point units (Optional); Interface to enter various set values via digital switches. ・ BCO: BCD parallel data output interface (Optional): Parallel interface to transmit weight data to a printer, external display, PC or sequencer. ・ 232: RS-232C communication interface (Optional): Write (change)/read weight data, various statuses and setting values from a PC or sequencer. ・ 485: RS-485 communication interface (Optional): Allows longer-distance communication than RS-232C. ID numbers are set, and multiple units of F701 are parallel-connectable. ・ DAC: D/A converter interface (Optional); Interface to convert weight data to current signal and output it. |
