Chapter 3 BCU I/O Module
40 BMTW-SVN01F-EN
Hardware UIP Selection
Each UIP has a set of hardware jumpers. Use the hardware jumpers on
the BCU I/O module to specify the input device type that the UIPs will be
configured for. The five UIP jumper sets are labeled UIP1 through UIP5.
Refer to Figure 13 on page 38 for jumper locations. Table 5 on page 39
lists input device types for each UIP along with their corresponding
jumper configurations, operating ranges, and circuit characteristics.
Binary/Pulse Meter Configured UIPs
Binary and pulse meter devices connected to binary configured UIPs
must be isolated and have ungrounded contacts. Binary hardware that
can be used includes momentary contact switches (normally open), stan-
dard (maintained) switches, and pulse metered devices (gas, water, or
electric).
Common devices are enthalpy switches, differential-pressure airflow
switches, system shutdown switches, remote alarms, photocell, gas
meters, water meters, and electrical demand meters.
For pulse meter devices, the closure pulse rate may range from 0 to 4 Hz.
On a contact closure, the minimum contact dwell time must last at least
125 ms for the closure to be recognized by the input.
For all UIPs in the BCU I/O module, you must create and set up the nec-
essary objects that will provide units, calculation, and alarming to the
desired input. Refer to the System Programming guide for creating and
setting up the necessary objects.
