Option description and instructions 31
If necessary, install additional reset buttons and indication lamps for the emergency stop
circuit on site. We recommend gold-plated NC contacts in the reset button. The maximum
allowed cable length between the drive and the reset button (for the whole loop) is 250 m
(820 ft). See the circuit diagrams of the delivery. Obey the general control cable installation
instructions given in the hardware manual and in
FSO-12 safety functions module user’s
manual (3AXD50000015612 [English]).
When a safety pulse encoder is used, ABB installs the FSO-21 and FSE-31 modules and
the wirings between the FSO module and the drive at the factory.
The user must wire the safety pulse encoder to the FSE module on site. Obey these rules:
•
Use a double-shielded, twisted pair cable.
•
The maximum allowed cable length between the safety pulse encoder and the FSE
module is 300 m (980 ft).
For more information, see FSE-31 pulse encoder interface module user’s manual
(3AXD50000016597 [English]).
Use of the safety function

Activating
1. Push the emergency stop button [S61]. The emergency stop activates and the button
locks in the “ON” (open) position.

Resetting
1. Make sure that the external start signal of the drive is switched off (it is possibly still on
if no pulse start is in use).
2. Turn the emergency stop button [S61] until it releases.
3. Push the emergency stop reset button [S62] on the cabinet door. The indication lamp
[P62] of the reset button [S62] goes off when you release the button.
4. Reset the drive if necessary.
5. You can now restart the drive.
Note : If you switch off the power after you have released the emergency stop button [S61]
(step 2), the drive resets the safety function automatically. In this case, you do not have to
push the reset button [S62].
