General Statement
The MP2+ system is intended for multiple low temperature process applications, for example paint spray booths or other curing processes. It is
ideal for multiple temperature critical and time sensitive process applications requiring temperatures from 60°F to 240°F.

Features
Initial Programming Menu
Programs
A maximum of (8) programs are available.
Each program has a maximum of (8) process set points.
The program and process set point in use is displayed as P(1-8) S#(1-8).
Programs utilize global settings.
Global Settings
Multiple programmable menu settings common to all programs (global)
to speed programming and insure consistent heater operation, program
to program.
Process Menu
Process Set Point
A maximum of (8) Process Set Points are available with a temperature
range of 60°F (15°C) to 240°F (115°C).
The Process Set Point is displayed as “SP.”
Process Set Points not being used can be turned to an “Off” setting.
Process Times (TM02 required)
Any of the (8) Processes can be timed. Each timed Process has a range of
00:00:01 to 23:59:59. The conclusion of a timed Process will immediately
proceed into the next Process. If the last Process of the program is timed, it
will proceed to the selected start position (see Looping Mode, page 7) after
timing out. The letter “T” will be displayed indicating a timed Process. Press
the up or down arrows on the TDM02 to scroll between the screens showing the Process Set Point and the sensed temperature AND the sensed
temperature with the time remaining in the Process (hh:mm:ss).
Operation Menu
Soft Start (Global Setting)
The Soft Start feature controls the initial rate of voltage change to the modulator. Soft Start operates when switching from a lower Process temperature to a higher Process temperature. It is designed to slow the initial input
rate to the burner. This feature is available in three settings: slow, medium,
and fast and may be turned off. “Ss” (slow), “Sm” (medium) or “Sf” (fast)
is displayed during the time the Soft Start is active. This feature is comprehensive to all Set Points.
Max Valve VDC (Global Setting)
This feature limits the maximum voltage applied to the modulator. It has a setting range of 7 to 25 VDC. This feature is comprehensive to all Set Points.

Features
Max Ramp VDC
This feature limits the maximum voltage applied to the modulator while
operating in the Ramping mode. It has a setting range of 5 to 24 VDC. This
setting cannot exceed the maximum voltage output setting. This feature is
comprehensive to all Set Points.
Total Bandwidth (Global Setting)
This feature determines the amount of temp. change required to drive the
modulator from the minimum fire setting to the maximum fire setting and
vice versa. This feature is used to eliminate pulsating or hunting due to an
oversensitive application. Increase the Bandwidth if a pulsating or hunting
condition exists for an extended period of time after a Set Point change.
The feature has a range of 5°F (2.8°C) to 15°F (8.3°C). Total Bandwidth is
comprehensive to all Set Points.
Offset Temp
This feature is used to maintain a desired temperature in an area not
being directly sensed by the MP2+ system. The average difference between the MP2+ sensed discharged temperature and the desired space
temperature must be known. This is the Offset. The Offset will set the
MP2+ sensed discharged air needed to produce the desired space temperature. Decrease (-) the Offset to maintain and control space temperature lower than MP2+ discharged temperature. Increase (+) the Offset to
maintain and control space temperature higher than MP2+ discharged
temperature. The space temperature will be displayed as the Process
Set Point.
Example
1 Program Offset to -5°F.
2 Program Process Set Point (desired space temperature) to 75°F.
3 Therefore discharge air temperature = 80°F.
(Required MP2+ discharge air temperature to maintain desired space temperature.)
4 The MP2+ discharged air temp. is 80°F. The displayed Process Set Point is 75°F.
80°F -5°F 75°F
The feature has a range of -10°F (-5.6°C) to +10°F (5.6°C) and is available for each Process.
Ramping
This feature is used to step the input rate when changing from one Process Set Point to another. It is available for each Process. The Ramping
Rate determines the amount of temperature change per hour in one-minute steps. It has a range of 60 Deg/hr to 900 Deg/hr. The change can be
positive or negative.

Features
Example
Process 1 = 75°F
Process 2 = 125°F
Process 2 Ramp Rate = 600 Deg/hr or 10 Deg/min
1 The control switches from Process 1 to Process 2.
2 The controller will immediately raise the temperature 10° and will hold it at the
new set point 85°F (75°F + 10°F) until 1 minute has passed.
3 It will continue to raise it 10° each subsequent minute until it meets Process 2.
4 It will take 5 steps (10°F each) and 4+ minutes to go from 75°F to 125°F.
This feature can be used with Max Ramp VDC and Soft Start to smooth the
stepping. (Soft Start only works when Process Temperature increases.)
“Ramp” is displayed to indicate the Ramping feature is active.
Timers
The controller features two Timers (Timer 1 and Timer 2) that accumulate
the hours of operation for each Process. Each Process has a Timer 1 and
a Timer 2. The TM02 is required.
Timer 1
Timer 1 logs the hours of operation for a Process. It will log up 999 hours
at which time it will automatically reset to zero. The hours can be user
reset to zero at any time. It also has a programmable alarm setting to notify the user (by flashing a character in the lower right hand corner of the
display) when the desired accumulated hours for the Process have been
reached. It has a setting range of 1 to 999 hours. The feature is useful in
maintaining maintenance requirements.
Timer 2
Timer 2 logs the hours of operation for a Process. It will log up 999 hours
at which time it will automatically reset to zero. The hours can be user reset to zero at any time. The feature is useful in maintaining maintenance
requirements.
Diagnostic Menu
Max Proc Temp (Global Setting)
This feature limits the maximum temperature for each Process. It has a
range of 60°F (15°C) to 240°F (115°C). It does not allow the Process Set
Point to be set in excess of the Maximum Process Temperature setting.
