Page 13: Muting Function
Control of the dangerous opening can be de-activated only by a correct sequence of interruption of the beams of the muting sensors. Figure 9 - Muting with SRS2M-2NO on palletizing system application example MUTING SEQUENCE The timing diagrams in Figure 10 and Figure 11 show the correct signal sequence. - Page 14 SRS2M-2NO SAFETY RELAY MUTING MODULE The muting enable command will only enable the muting function and should be generated at the appropriate time by the machine control system(e.g., when the muting function is needed); it has no effect on the deactivation of the muting function.

Page 15: Muting Override Function
Therefore, all operations must be carried out under the strict supervision of expert personnel. During the installation of the SRS2M-2NO safety relay module be sure to avoid short circuits between the contacts 7 and 8. The operator will use the override mode previously selected: 1. -
Page 16: Override With Pulse Control
SRS2M-2NO SAFETY RELAY MUTING MODULE OVERRIDE WITH PULSE CONTROL This function is activated inverting (maximum delay = 400ms) the condition of pin 7 and 8 of the receiver using for example a push button (switch). During the override, the 7 and 8 are not controlled. -

7. Operate a complete System Test. Table 5 The System Test is mandatory because a type 2 device is connected upstream to SRS2M-2NO safety module (e.g., photocell, safety photocell, etc). Refer to "THE SYS TEST COMMAND INPUT" INDUSTRIAL/SRS2M-2NO SAFETY RELAY MUTING MODULE... -
Page 20: Input And Output
The SYS TEST command (terminal 16) must be forwarded to the safety module connecting the terminal 16 to the +24VDC. The SYS TEST command must be sent to SRS2M-2NO connecting terminal 16 to the 24VDC for a time t>40 msec and remains operative as long as the terminal 16 is connected to 24VDC. -
Page 21: The Muting Enable Input
Muting status must be highlighted to the outside using an indicator light close to the guarded opening. SRS2M-2NO is equipped with a “MUTING LAMP” output (terminal 10) to which the indicator light can be connected and is able to monitor its correct operation and that it is present. -
