Thermal Probe
Connections
Four thermistor or 210E module inputs are provided on the
alarm termination board, and two thermal probe inputs are
provided at J1 and J3 on the BUJ1. These connectors will accept
standard Lineage Power thermal cables or 210E cables. J1 and
J3 provide cable access to RTH1 and RTH2 thermal probes,
respectively. If connections are made at J1 and J3 then they
should not be made at the terminal blocks and vice versa. Access
to all four thermistors is available at the terminal block. Each
thermistor is connected to the RTH#+ and RTN#, where # = 1
through 4. A strap is required across RTH#+ and EN#+ for each
thermistor input used. The strap is not required when using 210E
modules.
RTH ALM, RTH ALMR: Thermistor alarm input and return
from 210E module. See Section 4 for 210E module connections.
