The OPTAF option board together with VACON functions with VACON
®
NX family products.
NXP control board provides the following safety
Safe Torque Off (STO)
Hardware based ‘Safe Torque Off’ safety function to prevent the drive from generating torque on the motor shaft. STO safety function has been designed for use in accordance with the
following standards:
• EN 61800-5-2 Safe Torque Off (STO) SIL3
• EN ISO 13849-1 PL “e” Category 3
• EN 62061 SILCL3
• IEC 61508 SIL3
• The function also corresponds to an uncontrolled stop in accordance with stop category 0, EN 60204-1.
• EN 954-1, Category 3
vacon • 4 GENERAL
The STO safety function has been certified by IFA*
NOTE! Adequate protection from environment must be guaranteed. An adequate protection can be installation in an IP54 enclosure or the use of a drive with coated PCBs.
Safe Stop 1 (SS1)
SS1 safety function is realized in compliance with type C of the drives safety standard EN 61800-5-2 (Type C: “The PDS(SR) initiates the motor deceleration and initiates the STO function after an application specific time delay”). SS1 safety function has been designed for
use in accordance with the following standards:
• EN 61800-5-2 Safe Stop 1 (SS1) SIL3
• EN ISO 13849-1 PL "e" Category 3
• EN 62061 SILCL3
• IEC 61508 SIL3
• The function also corresponds to a controlled stop in accordance with stop category 1, EN 60204-1.
The SS1 safety function has been certified by IFA *
NOTE! Adequate protection from environment must be guaranteed. An adequate protection can be installation in an IP54 enclosure or the use of a drive with coated PCBs.
Motor Thermistor Over temperature protection (according to ATEX)
Overtemperature detection using thermistor. It can be used as a tripping device for ATEX certi-
fied motors. The thermistor tripping function is certified by VTT** according to ATEX directive 94/9/EC.
All safety functions of the OPTAF board are described in this user's manual. The OPTAF option board contains also two programmable output relays. (Note! Not part of any safety function.)
NOTE! The STO function is not the same as a prevention of unexpected start-up function. For ful­filling those requirements, additional external components are required according to appropriate standards and application requirements. Required external components may be for example:
• Appropriate lockable switch
• A safety relay providing a reset function
NOTE! The safety functions of the OPTAF board do not comply with Emergency Switching Off ac­cording to EN 60204-1.

OTE
VACON® NXP AC drive with IP54 enclosure.
Remove the main cover.
MAKE SURE THAT THE AC DRIVE IS SWITCHED OFF BEFORE AN OPTION OR FIELDBUS BOARD IS CHANGED OR ADDED!
C
Open the cover of the control unit.
vacon • 12 INSTALLATION OF THE OPTAF BOARD
D
Install OPTAF option board in slot B on the control board of the AC drive. Make sure that the grounding plate fits tightly in the clamp.
E
Cable installation:
STO and SS1 safety functions require the use of cable sealing grommets or glands for all cables in the drive. The grommets or glands must be suitable for the type and amount of cables used and they shall fulfill IP54 requirements.
F
See the User Manual for hole sizes for the Power cables. The hole size is PG21 (28.3 mm) for the control cables.
Close the cover of the control unit and attach the main cover. Before attaching the main cover, check that the gasket of the cover is not damaged for IP54 units. Use a tightening torque of 0.9...1.1 Nm for the main cover screws.
