Safety instructions 7 Safety instructions Contents of this chapter This chapter contains the safety instructions which you must obey when you install, operate and do maintenance on the safety functions of a drive. Use of warnings and notes Warnings tell you about conditions which can cause injury or death, or damage to the equipment.
8 Safety instructions Only a qualified electrician who has appropriate knowledge on functional, machine, and process safety is allowed to install, start up and maintain the safety circuit. All user-made changes are on the user's responsibility. WARNING! Always test the operation of the safety circuit according to its acceptance test procedure at the start-up and after any changes to the safety circuit.
The manual applies to ACS880-07/17/17LC/37/37LC drives which have the option: Emergency stop, stop category 1 with main contactor/breaker, with safety relays (option +Q952). For the option +Q952, ABB installs the FIO-01 digital I/O extension module (option +L501) to the drive. Target audience The manual is intended for people who install, start up, use and service the safety function.

12 Introduction to the manual Terms and abbreviations Term Description Cat. Classification of the safety-related parts of a control system in respect of their resistance to faults and their subsequent behavior in the fault condition, and which is achieved by the structural arrangement of the parts, fault detection and/or by their reliability. The categories are: B, 1, 2, 3 and 4.
This chapter describes the +Q952 emergency stop option and its settings. Overview The option +Q952 corresponds to a controlled stop in accordance with stop category 1 (EN/IEC 60204-1). After the user has given the emergency stop command, the drive first decelerates the motor(s) to zero speed according to a preset ramp time.

Option description 15 Step Operation The emergency stop safety relay [A61] switches off the digital input on the digital I/O extension module [A412.X] of the drive. This gives the emergency stop command. The emergency stop safety relay [A61] switches off the power for the timer relay [K61]. The break delay counter of the emergency stop safety relay [A61] starts (user-adjustable delay).

Electrical installation 25 Electrical installation Contents of this chapter This chapter describes the wiring of the safety option done at the factory and contains guidelines for making user connections (if any). Wiring One emergency stop button and one reset button are installed on the cabinet door and wired to the drive at the factory.
26 Electrical installation You can also install additional reset buttons and indication lamps for the emergency stop circuit on site. We recommend gold-plated contacts in the reset button. Wire the buttons to the appropriate terminal block inside the drive cabinet. See the circuit diagrams delivered with the drive.
Use of the safety function 27 Use of the safety function Contents of this chapter This chapter describes the use of the safety function with factory default settings.

36 Maintenance (high or low demand as defined in IEC 61508, EN/IEC 62061 and EN ISO 13849-1). Regardless of the mode of operation, it is a good practice to check the operation of the safety function at least once a year by doing the start-up and acceptance test of the safety function.
This safety data is valid for the default design of the safety circuit (as described in section Safety block diagrams below). In case the final design differs from the default, ABB calculates new safety data and delivers it separately to the customer.
