2 .2 Module carrier The module carrier provides fieldbus power for four fieldbus segments. It supports a pair of redundant pluggable power supply and arbitration modules for each segment and all connection facilities. Each carrier has connections for redundant 24V input power supplies, ALF111 fieldbus communication modules via AKB336 cables and intrinsically safe field trunks.
3 .3 . 1 Outdoor mounting If the assembly is to be mounted in an outdoor location, a suitable enclosure with a minimum of IP54 ingress protection is required. However, in some locations, a higher degree of ingress protection rating is recommended as corrosion resistance may be necessary or desirable and the emphasis should be placed on the suitability for the application.
3 .5 .2 Removing modules The FISCO power supply module must be removed before its related SAM module. 1. Loosen the two fixing screws of the FISCO power supply module and remove it from the circuit board. 2. Slide the red interlock tab on the SAM module to the side to reveal the fixing screw head. See Figure 3.4 3.
the ALARM connector at the top edge of the module carrier - See Figure 4.1. In normal operation, therefore, the ALARM terminals on the module carrier will present a nominal resistance value of 360Ω. If required, the alarm circuits of a number of 9108-22 assemblies can be daisy-chained to present a single alarm signal.
that is electrically bonded to the point of earthing of the local 230V AC power supply to the equipment cabinet that houses the FISCO power supplies. The two studs should be wired with separate cables, each having a cross-sectional area of 4mm or greater.
5 .2 Manual Failover testing Each Supply Arbitration Module (SAM) has a ‘Failover’ switch to test the functioning of the failover mechanism from Active to Standby power supply. This is for proof-testing of the power supply as part of a scheduled maintenance program. CAUTION Forcing a change of state of the active and standby modules by manually operating the ‘Failover’...
