These instructions do not supersede OEM’s installation or operating instructions. Installation, inspection, and replacement must be performed by a qualiﬁed installer or gas supplier.

This control must be electrically wired in accordance with local codes, or in the absence of local codes, with the National Electrical code, ANSI/NFPA 70 or the Canadian Electrical Code, CSA C22.1 as applicable.

General Statement

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

Features

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

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

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.

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

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.

Features

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.

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.

Features

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

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.

Min Proc Temp

This feature limits the minimum temperature for all Processes. It has a range of 60°F (15°C) to 240°F (115°C). It does not allow any Process Set Point to be set below the Minimum Process Temperature setting.

Calibration

This feature is used to ﬁne-tune a particular application. Calibration shifts the Bandwidth range up or down from the factory set mean. Each application is different with variances in burners and appliances. It can be necessary to change the midpoint of the modulation range to have the Process Temperature and the actual sensed temperature match.

For sensed temperatures consistently displaying lower than the Set Point, increase (+) Calibration by number of degrees off. For sensed temperatures consistently displaying higher than the Set Point, decrease (-) Calibration by number of degrees off. It is available for each Process and has a range of –10°F (-5.6°C) to +10°F (5.6°C).
