Load Controller Software Update: Version 0140 to 0150 (continued)
Load output, modulating
• < 3 mA: Line interruptio
n
• 4 mA: 0% load
• xx mA: Low fire (minimum load)
• xx mA: Nominal load (maximum load)
• 20 mA: 100% load
• Shutting the burner down = no impact on signal.
Manipulated variable input, multistage burner
• Stage 1: 5 mA or 2.5 Vdc
•
Stage 2: 10 mA or 5 Vdc
• Stage 3: 15 mA or 7.5 Vdc
Switching thresholds at:
• 7.5 mA and 12 mA with 0.5 mA hysteresis
• 3.75 Vdc and 6.25 Vdc with 0.25 Vdc hysteresis
Load output, multistage
• Burner off: 4 mA
• Stage
1: 5 mA
• Stage 2: 10 mA
• Stage 3: 15 mA
Load Controller Software Update: Version 0150 to 0160
The following updates were made with L
MV5 load controller software version 0160:
1. The plausibility check at inputs X61 and X62 is not made anymore. This means that fast value
changes at these inputs will no longer result in a safety shutdown.
Load Controller Software Update: Version 0160 to 0180
The following updates were made with L
MV5 load controller software version 0180:
1. Analog inputs 2 and 3 (X61, X62) have two additional ranges added: 0-10 Vdc and 0-20 mA.
