5.2 Interface Modules - ML100 & MR100
The ML100 Dedicated Interface Module is capable of pro-
gramming and monitoring one Control Module such as the
MS-10A. It is a “Dedicated” interface because it connects
to only one Control Module. It is designed to be door-
mounted in a NEMA-4 enclosure in an industrial environ-
ment. Operator interface is through the Status Indicators,
LCD Display and the Keypad. Refer to Figure 5.8 and Fig-
ure 5.9.
The MR100 Group Interface Module is capable of program-
ming and monitoring from one to thirty Control Modules. It
is a “Group” interface because it connects, via a serial cable
to several Control Modules. It is designed to be door-
mounted in a NEMA-4 enclosure in an industrial environ-
ment. Operator interface is through the Status Indicators,
LCD Display and the Keypad. Refer to Figure 5.8 and Fig-
ure 5.10.
5.2.1 Status Lights Located on Circuit Board :
• L8 Transmit: LED flashes when the Interface Module is
transmitting information to the data highway. MR100 only.
• L9 Receive: LED flashes when the Interface Module is
receiving information from the data highway. MR100 only.
5.2.2 Switches and Jumpers:
• S3 Program Enable: When the Program Enable dip switch
is set to DISABLE, programming is disabled and setpoints
and configuration cannot be changed. Otherwise, pro-
gramming is allowed.
5.2.3 Terminals: Refer to the Typical Wiring Diagrams
for power field connections.
• T14 Alarm Contacts: In hazardous areas the dc output
is rated 30Vdc @ 0.1A (terminals 906 and 907) and the dry
mechanical output is rated 30Vdc @ 10mA, 250Vac @
0.5A (terminals 904 and 905). In ordinary areas the dc
output is rated the same as hazardous but the dry me-
chanical output is rated 120Vac @ 1A, 30Vdc @ 0.1A.
Contacts are configurable for normally open or closed.
MR100 only.
• T15 Alarm Light Output: The output is configurable or
normally open, closed or flash. Output is rated 12 Vdc @
30 mA for an LED type lamp (terminals 909+ and 908-).
MR100 only.
• T16 Control Power Input:120Vac input (terminals 902 and
903), earth ground (terminal 901). MR100 only.
• T17 Power OUT/IN terminals: Terminals 913 (POUT) &
914 (PIN) are designed to interface with 3rd party 4-20mA
RTD Transmitter for temperature measurement. 913 (+15V)
is dc current source terminal and 914 is dc current return
terminal. To connect with an RTD Transmitter, use 18
AWG wires to connect terminal 913 to the I(+) terminal on
RTD Transmitter, and terminal 914 to the I(-) terminal on
RTD Transmitter. The actual RTD sensor is to be locally
wired to the RTD Transmitter and the transmitter can be
located up to 7km away from MR100. Refer to Appendix E
for the operation detail of RTD Transmitter. MR100 only.
5.2.4 Communications Port:
• C4 Parallel Port: Standard connection to a single Control
Module via a ribbon cable. Maximum cable length is five
feet. ML100 only.
• C5 Serial Port : Standard connection to an RS-485 data
highway via a 2-conductor, shielded, twisted pair cable.
Maximum Cable length with 30 Control Modules without
repeater is 4,000 feet. (terminals 912+, 911-, 910 SHD).
MR100 only.
5.2.5 Trim Potentiometers:
• P1 LCD display: Adjusts the contrast according to the
viewing angle.
5.2.6 Status Lights Located on Faceplate :
• L10 Power: The green Power light should be on at all
times indicating that control power is applied to the In-
terface Module. If the light is off either there is no volt-
age across terminals 902 and 903 or the Interface Module
has a malfunction and requires servicing.
• L11 Heater: The green Heater light is on if the selected
heater is energized.
• L12 Communicate: Random flashing of the green Com-
municate light indicates that serial communications are
active on the Control Module to which it is connected.
• L13 System Fail: The red System Fail light should be off,
indicating that the system check was successful. On the
Dedicated Interface Module, if the light is on, the Control
Module has failed its self-test and requires servicing. On
the Group Interface Module, if the light is on, the Group
Interface Module has failed its self-test and requires serv-
icing.
• L14 Alarm: The red alarm light is off when there are no
alarms. The light will flash if any alarm conditions are
present. Press [STATUS] to view alarms.
5.2.7 Alphanumeric Display:
• D1 Display: Two lines with sixteen alphanumeric charac-
ters per line. It is backlit for viewing in low-light condi-
tions.
5.2.8 Keypad:
• K1 Interface Module Keypad: Consists of nine keys
which, when used in connection with the Alphanumeric
Display, allow complete control of programming and moni-
toring of any Control Module connected to the Interface
Module.
