9 Application Examples
Programming example 1
Par. 5-19 Terminal 37 Safe Stop
[4] PTC 1 Alarm
Par. 5-15 Terminal 33 Digital Input
[80] PTC Card 1
Alternatively, par. 5-19 could be set to selection [5] (PTC 1 Warning), what means an automatic restart when the conditions of the PTC circuit have
returned to acceptable. The choice depends on customer demands.
Combination with other component using Safe Stop

Programming example 2
Par. 5-19 Terminal 37 Safe Stop
[6] PTC 1 & Relay Alarm
Par. 5-15 Terminal 33 Digital Input
[80] PTC Card 1
Alternatively, par. 5-19 could be set to [7] (PTC 1 & Relay Warning), what means an automatic restart when the conditions of the PTC circuit and/ or
emergency stop circuit have returned to normal. The choice depends on customer demands. Also, the setting of parameter 5-19 could be [8] (PTC 1 &
Relay A/W) or [9] (PTC 1 & Relay W/A), which are combinations of alarm and warning. The choice depends on the customer needs.

In case the motor temperature is too high or in case of a PTC failure, the MCB 112 activates the Safe Stop of the FC
302 (Safe Stop terminal 37 goes LOW (active) and digital input 33 goes HIGH (active)). This parameter decides the
consequence of the Safe Stop. With this choice the FC 302 coasts and "PTC 1 SafeStop [A71]" is displayed in the LCP.
The drive must be manually reset from LCP, digital input or fieldbus when the conditions of the PTC are acceptable
again (temperature of motor has dropped)
Connects the Digital Input of terminal 33 in the FC 302 to the MCB 112 which makes it possible for the MCB 112 to
indicate when Safe Stop has been activated from here

of the FC 302 (Safe Stop terminal 37 goes LOW (active) but digital input 33 is not triggered by MCB 112 X44/ 10
as the MCB 112 did not need to activate the Safe Stop, hence digital input 33 remains HIGH (inactive)).
