Table 3-10 - Temperature vs. Resistance Coefficient

The UCM network relies on various sensors located throughout the system to provide temperature information in the form of an analog input. All of the sensors used have the same temperature vs. resistance co-efficient and are made from Keystone Carbon D97 material with a 1 degree Centigrade tolerance.

Emergency Stop Switch (5S71)

A normally closed (N.C.) switch (5S71) wired to the RTM may be used during emergency situations to shut down all unit operations. When opened, an immediate shutdown oc- curs. An emergency stop diagnostic is entered into the Hu- man Interface and the unit must be manually reset. Refer to the appropriate illustrations in Figure 3-16 or 3-17 for the proper connection terminals in the unit control panel. The switch must be rated for 12 ma @ 24 VDC minimum.

Occupied/Unoccupied Contacts (5K86)

To provide Night Setback control if a remote panel with NSB (5U58) was not ordered, a field supplied contact (5K86) must be installed. This binary input provides the Occupied/ Unoccupied status information of the building to the RTM. It can be initiated by a time clock, or a Building Automation System control output. The relay’s contacts must be rated for 12 ma @ 24 VDC minimum. Refer to the appropriate il- lustrations in Figure 3-16 or 3-17 for the proper connection terminals in the unit control panel.

Demand Limit Relay (5K89)

If the unit is equipped with a Generic BAS Module (1U51), (i.e. unit model number digit 21+ is a “K”), a normally open (N.O.) switch may be used to limit the electrical power us- age during peak periods. When demand limit is initiated, the mechanical cooling and heating operation is limited to either 50% or 100%. Demand limit can be initiated by a toggle switch closure, a time clock, or an ICSTM control output. These contacts must be rated for 12 ma @ 24 VDC mini- mum.

Outside Air Sensor (3RT3) - BAYSENS016A

This device senses the outdoor air temperature and sends this information in the form of an analog input to the RTM. It's factory installed on units with an economizer, but can be field provided/installed and used for informational purposes on units without an economizer. Refer to the appropriate il- lustrations in Figure 3-16 or 3-17 for the proper connection terminals in the unit control panel. Refer to Table 3-10 for Temperature vs Resistance coefficient.
