Ems Input Mode; Stage Interface - heat-timer Multi-MOD Platinum Installation And Operation Manual

• The 4-20ma option is used with the 4-20mA temperature sensor
(HT# 904160-00) . These sensors can be configured to read temperatures
up to 480°F / 268°C . The user must set the 4ma and 20ma temperature
range to match the sensor configuration . These sensors' ranges must be
set by Heat-Timer . See "4-20mA Temperature Sensor Wiring" on page 18 .
• Values that are higher than 21 .6mA shall read SHORT . Values that are
lower than 2 .4mA shall read OPEN .

• Setback allows the Set Point to be adjusted manually .
• EMS Control allows the set point to be sent remotely using 4-20mA
signal . The set point range must be set to match the EMS signal's set
point range using the 4mA and the 20mA temperature settings . See
"External Set Point Wiring" on page 22 .
• An active signal must be between 2 and 22mA . Any signal out of this
range shuts down the system and displays "Shutdown by EMS" .

• These options are designed for Modbus operating burners equipped
with the Siemens LMV controller . If the burner did not have Modbus
communication, then select Normal .
• The MODBUS-Monitor Only option receives the alarm lockout status
through the Siemens LMV Interface .
• The MODBUS-Full Control option sends the modulation percent and
receives the lockout status through the Siemens LMV Interface .
• Order the LMV Interface for each of the MODBUS burners
(HT# 926621-00) . In addition, order the Interface Power Supply
(HT #926622-00) for every 10 burners . See LMV-Interface Manual .
• When any of the Modbus options is selected from the Stage Interface
menu, the Stage Modbus Address will follow .
• Each Stage address must be unique on the Modbus network .
• To exit the Stage Modbus Address, enter an address of 0 for the stage
following the last stage .

• The Multi-MOD Platinum has two Modulating Output Cards . Each card
modulates two stages . Both stages must use the same modulating
signal . See "Modulating Output Card Installation" on page 23 .
• Output Cards can be either 135Ω Cards for 135 ohm modulating motors
or Current/Voltage Cards for current or voltage signal operating motors .
