MODULAR SAFETY INTEGRATED CONTROLLER MOSAIC RESTART_FBK The RESTART_FBK signal input allows the MOSAIC to verify an EDM (External Device Monitoring) feedback signal (series of contacts) from the external contactors, and to monitor <strong>Manual</strong>/Automatic operation (See the list of possible connections in Table 16). If the application requires it, the response time of the external contactors must be verified by an additional device. The RESTART command must be installed outside the danger area in a position where the danger area and the entire work area concerned are clearly visible. It must not be possible to reach the control from inside the danger area. 24V K1 K2 ext_Restart_fbk 24V ext_Restart_fbk 24V K1 K2 ext_Restart_fbk 24V ext_Restart_fbk Table 16 English 28 8540780 • 12/01/2016 • Rev.25
MODULAR SAFETY INTEGRATED CONTROLLER MOSAIC OUT STATUS The OUT STATUS signal is a Programmable signal output that can indicate the status of: • An input. • An output. • A node of the logic diagram designed using the MSD. OUT TEST The OUT TEST signals must be used to monitor the presence of short-circuits or overloads on the inputs (Figure 6). The maximum number of controllable inputs for each output OUT TEST is: - 2 INPUT (parallel connection) - 4 INPUT (parallel connection) The maximum allowed length for OUT TEST signal connections is = 100m. Figure 6 OSSD (M1, MI8O2) The OSSD (static semiconductor safety outputs) are short circuit protected, cross circuit monitored and supply: • In the ON condition: (where Uv is 24V ± 20%) • In the OFF condition: The maximum load of 400mA@24V corresponds to a minimum resistive load of 60. The maximum capacitive load is 0.82F. The maximum inductive load is 2mH. OSSD (MO2, MO4) The OSSD (static semiconductor safety outputs) are short circuit protected, cross circuit monitored and supply: • In the ON condition: (where Uv is 24V ± 20%) • In the OFF condition: The maximum load of 400mA@24V corresponds to a minimum resistive load of 60. The maximum capacitive load is 0.82F. The maximum inductive load is 2mH. It is not allowed the connection of external devices to the outputs, except as expected in the configuration performed with the MSD software. Each OSSD output can be configured as shown in Table 17: The output is activated according to le configurations set by the MSD SW only if the corresponding RESTART_FBK input is conected to 24VDC. The output is activated according to le configurations set by the MSD SW only if corresponding RESTART_FBK input FOLLOWS A LOGIC TRANSITION OF The output is activated according to le configurations set by the MSD SW only if the corresponding RESTART_FBK input FOLLOWS A LOGIC TRANSITION OF English Table 17 8540780 • 12/01/2016 • Rev.25 29
