Emerson Site Supervisor - Hand-Held Terminal (P;N 814-3110)

I/O Board Names and Terminology RS485 I/O Network Boards and Peripherals • 2-7
eight stepper motor valves, which are typically used to
control temperature.
The MultiFlex ESR uses suction side variable-position
evaporator regulators (ESRs) to vary evaporator pressure
for an entire circuit and is an alternative to mechanical
EPR control.
The MultiFlex ESR receives input data from a Retail
Solutions Site Supervisor controller (via the I/O Network)
and then regulates the stepper valves according to the data
from the Site Supervisor.
Each MultiFlex ESR board requires a Class 2, 80VA
24VAC center-tapped transformer for power. Retail
Solutions transformer (P/N 640-0080) is a multi-tapped
primary transformer that may be used with the MultiFlex
ESR board.
2.2.7 Hand-held Terminal (P/N
814-3110)
The Hand-held Terminal (HHT) is used by
manufacturers and service technicians to diagnose and test
several of Retail Solutions' existing and legacy products.
The HHT can be used on any Retail Solutions product
with an RJ-11 connector. The most common applications
include:
• All MultiFlex I/O boards and the 8ROSMT
• All Gateway boards
• Stand-alone MultiFlex boards (RTU, RCB, PAK,
CUB)
• CCB and CC-100 case controllers
The HHT does not require a separate power source.
The unit is powered from the RJ-11 connector on the
peripheral equipment. The HHT includes a standard male
RJ-11 to male RJ-11 cable.
2.2.8 The 8RO and 8ROSMT Relay
Boards
The 8RO (P/N 810-3005) board is a general-purpose
board used to connect an Site Supervisor to any of eight
standard control relay outputs, but is now obsolete and has
been replaced by the 8ROSMT (P/N 810-3006) board.
To function, the 8RO board must be connected through
either the Echelon Network or the RS485 I/O Network to
the Site Supervisor. When properly installed, the 8RO
receives an electrical impulse from the Site Supervisor,
which either opens or closes any of eight contact relays.
Output definitions within the Site Supervisor allow the
user to configure the 8RO board to interact with any
refrigeration system or environmental control component.
The 8RO board is the direct link between the Site
