7.4.1 Checking the warm-up function in low-temperature conditions
When operating in low ambient temperatures, start-up of the machine is performed via an automa‐
ted start-up process.
When the «START» key on the control panel of the SIGMA CONTROL SMART is pressed, the en‐
gine begins a maximum of three automatic start-up cycles of 30 seconds each.
Following every false start, the machine is vented. Following each time the machine is vented, a
new start-up cycle begins automatically.
Should the third start-up cycle end with another false start, the operator must manually switch off
the control voltage and, after a defined period of time, switch it back on again.
➤ Follow all instructions carefully.
