AC031S/32S safety monitor:

New functionality

SAFETY AT WORK

Date: 5/18/2009

Feature #1: Control of safety output modules

Application: Shut off multiple motors on a single conveying zone

Advantage: Safety output module reduces wiring complexity; less wire to run back to main control panel.

Feature #1: Control of safety output modules

Typical configuration layout shown above.

AC031S or 32S has an additional integrated node built into the safety monitor located at terminal AS-IS

AC031S/32S

1 2 3 4 5 6 7

Feature #1: Control of safety output modules

In order to control the safe output modules, the AS-IS terminals must be wired back to the AS-I + and -

AS-IS is treated like a safety node and will take an address on the current network. You might need to reconfigure the AS-i master when the AS-IS terminal has been addressed.

AC031S/32S

Feature #1: Control of safety output modules

The address for the AS-IS terminal is given in the ASIMON software v3.00 or greater (as shown above).

In this example, we will provide an address 29. Note: This address is NOT the monitor address! For feedback indication, a safety monitor address can be given as well. The monitor address and AS-IS address are two separate entities.

Address selection for the AS-IS terminal*Make sure to check “Actuator”

Feature #1: Control of safety output modules

Whether you use the AC031S or AC032S monitor, you must have logic in the 2nd OSSD (2nd safety zone) to control the safety output modules. The safety output modules will follow this logic. In our example, this is the logic for the AS-IS terminal; address 29.

AC030S safety output modules are control by the logic in the 2nd OSSD

Feature #1: Control of safety output modules

The AC030S has a small dip switch on the front of the unit for programming the addresses on the unit. R= Run or P=Program

In run mode, the module will act as a extended addressing module with 4 standard non safe inputs (This is the normal operation mode)

In program mode, you will teach the address of the safety monitor (AS-IS) you want the module to listen to. *Note: This address will not take a physical address on the AS-I system

Switch back into run mode when complete

AC030S

Feature #1: Control of safety output modules

In the above example, 2- AC030S have been added to the system to safely shut off motors.

In normal operation, the 2- AC030S modules above will mimic the 2nd safety zone of the safety monitor. Both units are listening and will change state based on the AS-IS terminal addressed at 29.

AC031S/32S

Feature #2: Communication to a second SAW network

Application: Communicate status to a second SAW network for global shutdown of both systems

Advantage: In the past, a separate safety module was required on the second network to perform the same task. This has been eliminated with the new safety monitors.

Feature #2: Communication to a second SAW network

Typical configuration above with two separate safety networks

AC031S or 32S has an additional integrated node built into the safety monitor located at terminal AS-IS

Feature #2: Communication to a second SAW network

The AS-IS terminals are wired to the AS-I + and – of the second safety network

In the example, node 29 (AS-IS) will now appear in the second safety network.

Feature #2: Communication to a second SAW network

The AS-IS terminals are wired to the AS-I + and – of the second safety network

In the example, node 29 (AS-IS) will now appear in the second network.

Address selection for the AS-IS terminal*Make sure to check “Input Slave”

Feature #2: Communication to a second SAW network

The address of the AS-IS terminal will act like a standard safety slave on the second safety network.
