9.7 Soft-Start Function
To safeguard the life of the heating elements that require preheating, the REVO RT has the Soft start function,
available in 2 modes:
• Gradient
• Percentual
Both modes perform a preheating, avoiding potentially harmful thermal shocks to the heating elements.
During the activation of Soft Start function the parameter 1216 goes to value “5”
Gradient:
When the regulator is turned on or enabled via digital input or via serial command, the Set Point is reached
by following the rising gradient set on the "Gradient Soft-start" parameter:
• P241 Add 2241 = in Unit/hour (°C/h) for Loop 1
• P251 Add 2251 = in Unit/hour (°C/h) for Loop 2
• P261 Add 2261 = in Unit/hour (°C/h) for Loop 3
until the temperature set in the "Soft-Start Threshold" parameter is reached
• P243 Add 2243 = Set Point Soft start for Loop 1
• P253 Add 2253 = Set Point Soft start for Loop 2
• P263 Add 2263 = Set Point Soft start for Loop 3
or when the time set in the “Soft-Start Time” parameter has elapsed.
• P244 Add 2244 = Soft start time (hh.mm) for Loop 1
• P254 Add 2254 = Soft start time (hh.mm) for Loop 2
• P264 Add 2264 = Soft start time (hh.mm) for Loop 3
Percentual:
When the regulator is turned on or enabled, the output goes to the
power set in the parameter “Soft-Start Percentage”
• P242 Add 2242 = Output Soft Start percentage (0
÷ 100%) for Loop 1
• P252 Add 2252 = Output Soft Start percentage (0 ÷ 100%) for Loop 2
• P262 Add 2262 = Output Soft Start percentage (0 ÷ 100%) for Loop 3
until the temperature set in the parameter “Soft-Start Threshold” is reached,
• P243 Add 2243 = Set Point Soft start for Loop 1
• P253 Add 2253 = Set Point Soft start for Loop 2
• P263 Add 2263 = Set Point Soft start for Loop 3
or when the time set in the parameter “Soft-Start Time” has
elapsed (Par 244, 254, 264).
• P244 Add 2244 = Soft start time (hh.mm) for Loop 1
• P254 Add 2254 = Soft start time (hh.mm) for Loop 2
• P264 Add 2264 = Soft start time (hh.mm) for Loop 3
NOTE: If the Sof-Start function is active the automatic/manual
Tuning function cannot be activated.
