If the Enable-Mode is set to SW, the logic of the Start-Button is not bypassed
(Enable-Mode switch open). Consequence: HW-ENABLE and Start-Button
only together are activating the Final-ENABLE.
CD-RESET
– Input (X2-2)
Control Digital
– HW-RESET (Hardware-Reset)
Input
resistance: 10 kΩ (pullup)
Digital TTL (5 V) input. High if left open.
Default configuration: low active
With HW-RESET internal error states can be cleared (see Error states).
Note:
The HW-RESET input is not a reset line for the MCU.
CD-READY
– Output (X2-3)
Control Digital
– READY
Output resistance: 330
Ω
Digital TTL (5 V) output.
Default configuration: high active
The output signal READY indicates that the TEC-Controller is working
normally and that there are no error states.
READY = inactive:
after power on: TEC-Controller is booting. Internal peripherals are put
into operation.
An error is present (i.e. broken temperature sensor).
READY = active:
TEC-Controller is in normal working condition. No errors present.
