Installation notes
- Redundant SZ Controllers can install on the SZ Controller Carrier or on the Dual Universal Safety Carrier.
- SZ Controllers receive redundant 24 VDC input power through the SZ Controller Carrier or the Dual Universal Safety Carrier.
- SZ Controllers connect to the Area Control Network and to the Local Safety Network through the Ethernet Isolation Ports (primary and secondary) on the SZ Controller Carrier or the Dual Universal Safety Carrier.
- Redundant Modbus TCP ports on the SZ Controller Carrier enables the SZ Controller to support standalone SIS installations.
- A physical keylock switch on the SZ Controller Carrier along with an unlock software function restricts how and when the associated CSLSs can be unlocked for downloads and upgrades.
