SIGNALS
INPUTS
MASTER_ENABLE
The base unit MSC-CB has two inputs: MASTER_ENABLE1 and MASTER_ENABLE2.
These signals must both be set permanently to logic level 1 (24 VDC) so that the
MSC system functions correctly. If you need to deactivate the MSC system, these in-
puts can be set to logic level 0 (0 VDC).
NODE_SEL
The inputs NODE_SEL0 and NODE_SEL1 (on the expansion modules) are used to assign an
address to the expansion modules using the connections given in Table 12:
Table 12
Two modules of the same type are not allowed to be assigned the same address.
