Functions

Table 4.1:

Overview of the safety functions

4.1

Start/restart interlock

(Connection of the reset button between pin OUT / 24 V and pin SR of the MSI-MC310)
(Connection of the reset button between pin A2 and pin SR1 / SR2 of the MSI-MC311)
The start/restart interlock prevents automatic release of the safety circuits and automatic start-up of the              

system (e.g., if the protective door closes again or an interruption of the voltage supply is restored).
The system may not be manually released with the reset button until no persons are located in the danger                  

zone (see chapter 7.7 „Unlocking start/restart interlock“).

4.2

Automatic start/restart

(Bridge between pin OUT / 24 V and pin A of the MSI-MC310)
(Bridge between pin SR1 / SR2 and pin EDM of the MSI-MC311)
The automatic start/restart interlock enables immediate release of the safety circuits and automatic start-             

up  of  the  system  (e.g.,  if  the  protective  door  closes  again  or  an  interruption  of  the  voltage  supply  is                  

restored).
This operating mode is only permitted if it is not possible to reach or step behind the guard (see chapter 7.7                    

„Unlocking start/restart interlock“).

4.3

Contactor monitoring (EDM)

(Connection in the start circuit between pin OUT and pin SR of the MSI-MC310)
(Connection in the start circuit between pin S12 and PIN EDM of the MSI-MC311)
The MSI-MC310 / MSI-MC311 monitors the feedback circuits of the connected relays or contactors.

The two OSSDs are not activated until:

• all actuators of the connected sensors are in the specified distance range
• all connected sensors are activated
• opening of the contacts (reset button, EDM contacts) causes the signal at pin SR to drop out

Short description of the functions

Stop function

Safety-related; initiated by the guard

Start/restart interlock

Prevents automatic restart; forces manual confirmation via a reset button 

(RES)

Automatic start/restart

Automatic operation without use of a reset button 

RES (restart)

Manual start by means of a reset button for guards that are accessible 

from behind

EDM

External Device Monitoring (contactor monitoring)

Display technology

LEDs, display for K1, K2 input condition as well as for voltage supply

OSSDs

Safety-related switching outputs (relays)
