RM1000 SERIES
Description
The RM-1000 Series is a motor-monitoring device to be used in
conjunction with the 777 family of products (excluding the P1
Series), 77C family of products and the 601 voltage monitors,
via Modbus protocol with a communications module. The
RM-1000/777 motor management system combines
unsurpassed electronic motor protection and critical, user-
friendly, motor monitoring.
The RM1000 Series can monitor up to 16 MotorSaver® and/or
PumpSaver® units through an RS-485 network using Modbus
RTU protocol. A second communication port allows monitoring
and control of up to 99 MotorSaver® and/or PumpSaver® units
from a computer, PLC, DCS or SCADA system and can be
accessed from the host computer or PLC with the RM1000
acting as a repeater for any of its motor protectors. In addition
to the monitoring functions, the RM-1000 can be used to reset a
tripped MotorSaver® or PumpSaver®.
The RM1000 Series is easily mounted remotely and improves
safety for service and operations personnel by allowing them
to control and monitor the device without opening the electrical
cabinet. Using the RM1000 is a simple, cost-effective method
for aiding compliance with arc flash safety regulations. The
enclosure and keypad assembly is water and ultraviolet light
resistant. The enclosure is NEMA 3R or NEMA 4X (optional)
rated. The RM1000 and RM1000 NEMA 4 also carry a UL Type
12 rating, whereas the RM-1000-3R does not carry the UL Type
12 rating due to added weep holes. The added weep holes in
the RM1000-3R make it suitable for applications subjected to
condensing moisture/humidity.
