Description

ABB Stalectronic 700 SE700 Refrigeration Control System Training Manual

This ABB Stalectronic 700 training manual is the complete document set issued by the ABB Refrigeration AB Training Center for the SE700 electronic control system used on Stal refrigeration compressors and compressor units. It explains the Operator’s Panel (OP), the Compressor Control Unit (CCU), the RS232C and RS422/485 communication ports, the StalExcom open protocol, the philosophy of control behind the SE700, and the ABB SAMI GS frequency converter that drives the compressor motor. The same document also covers the external Danfoss AKS 32/33 pressure transmitters and PT100 temperature sensors that feed the system, making it a single reference for the whole SE700 measurement, regulation, and sequencing chain.

Read together, these chapters give the technician a full working picture of the Stalectronic 700 system: what each board and terminal does, how the Operator’s Panel talks to the Compressor Control Unit over RS232C, how the RS422/485 and RS485 buses daisy-chain up to eight compressor units for sequence control, how the StalExcom protocol exposes Boolean, Real, and Integer data sets to a supervisor PLC or PC, and how the SAMI GS frequency converter is parameterised to match the SE700 and the ABB high-speed motor. The document does not stop at theory — it also gives fault-tracing flowcharts, terminal-by-terminal wiring references, sensor scaling examples, and the replace-and-recommission procedure for the OP and CCU.

What This ABB Stalectronic 700 Manual Enables You to Do

With this manual on hand you can start up, configure, and diagnose an SE700-equipped Stal refrigeration compressor without guesswork. The Function Configuration chapter walks through every menu question — controller input type (temperature, pressure, or pressure-as-saturated-temperature), external start input behaviour, capacity control input use, step-up/step-down delay times, sequence order, alarm enable/disable for discharge pressure when not running, and sensor scaling in bar(a) and °C. The Operator’s Panel chapter tells you which key calls up which display, how alarms are acknowledged and reset, how the backlight and contrast behave, and how the VALUE LIST cursor is used to change a parameter. The CCU chapter documents each analog and digital I/O point by terminal number, so wiring the solenoid valves, oil heater, motor heater, thermistor relay, discharge pressostat, capacity sensor, and the sequence/compressor/minimum-pressure sensors is a matter of following the printed tables rather than tracing cables by hand.

For maintenance and troubleshooting, the fault-tracing sections are the practical core of the ABB Stalectronic 700 SE700 documentation. The manual explains what each flashing or steady LED means on the OP and CCU, how to interpret the 24 V AC and 5 V rails, how to test a Stal pressure sensor by measuring 1–5 V DC across the 250 Ω measurement resistor, how to verify a PT100 four-wire sensor against the IEC 751 resistance table, and how to check the compressor capacity sensor’s ZERO and SPAN potentiometers. It also covers the SAMI GS fault codes — overcurrent, overvoltage, undervoltage, motor stall, motor temperature, earth fault, analogue input below 2 V/4 mA, EEPROM write failure, and internal communication faults — with the probable cause and the correct reset method for each.

Why Correct Procedures and Specifications Matter Here

The SE700 is not a generic controller. Its analog inputs are selectable between 0–10 V and 0/4–20 mA only by physically moving jumpers in the strapping interface connector; its sequence controller only works when every CCU on the RS485 daisy chain has a unique binary address and the two end units are terminated with JMP4/JMP5 set to ON; and its capacity controller output is filtered through a ramp delay whose 1.0 %/s default protects the compressor from being slammed open. Getting any of these wrong does not simply degrade performance — it can drive the slide valve past its mechanical limits, trip the motor on overcurrent, or leave the sequence controller unable to see its slaves. This training manual is the document that spells out those settings, the reference values behind them, and the consequences of ignoring them.
