PME71.
901A1
558 UDS Mode
This parameter is for Siemens use only.
0 = PC tool mode
1 = PWM mode
2 = actuator mode
3 = internally
4 = internally
5 = internally
•
559 Speed Control Mode 1 0-2
This setting activates or deactivates the internal PID control in the LME7. If using a PWM blower that has
its own internal speed control, this should be deactivated.
0 = deactivated
1 = activated
2 = test mode
•
560 Ratio Control Mode
Defines the device being controlled by the LME7 that is used to influence the amount of air to the burner.
This value is set by Siemens and cannot be modified. On PME71.901A1, this value should always be set to
1.
0 = none
1 = PWM blower
2 = actuator
•
644 Feedback Pulse / Rev 3 2-5
This sets the expected number of pulses per revolution being output from the PWM blower. This
information should be provided by the blower manufacturer.
•
646 Settling Time 2.058 sec 1.029-2.058 sec
The blower speed must lie within tolerance band 1 for this length of time before the target speed is
considered reached.
•
650.00 Tolerance Band 1 +/- 1% +/- 1-5%
Sets an inner tolerance band for blower speed control. Percentages are based on the maximum blower
speed (parameter 519). If the actual blower speed falls outside tolerance band 1 for longer than the time
set by parameter 660, a lockout occurs.
•
650.01 Tolerance Band 2 +/- 3% +/- 1-10%
Sets an outer tolerance band for blower speed control. Percentages are based on the maximum blower
speed (parameter 519). If the actual blower speed falls outside tolerance band 2, a lockout occurs
immediately.
•
654 Analog Input S 1 0-5
Sets the type of input signal being connected to terminal X65 or X5-03. This input signal is used to
determine the blower speed during operation.
0 = 3-position
1 = 0-10 VDC
2 = 0-135 Ohm
3 = 0-20 mA
4 = 4-20 mA with lockout when input is less than 4 mA
5 = 4-20 mA without lockout when input is less than 4 mA
•
658.00 PWM Startup S/O 25% 1-100%
Sets the minimum PWM signal that the blower needs to receive in order to start the blower from
standstill. This information should be provided by the blower manufacturer.
