Undervoltage Overvoltage	Supply voltage is out of range.	Please contact EVSE installer.
Charge with ventilation	EV requests “Charging with ventilation” and “Charging with ventilation” is not enabled on EVSE	Enable “Allow charging with ventilation” if charged EV is located in ventilated area.
PS reading error	No communication with internal power sensor.	Please contact the service department of your EVSE supplier.
Current is higher than allowed	Vehicle draws more power than allowed.	Please try to charge another EV, if error still appears, please contact the service department of your EVSE supplier. Otherwise, please contact an authorized car service department.

EVSE configurator, for details please read Robotina charger
2. Other EVSE (charging station) linked to Robotina charger
Robotina charger could have up to 7 charging stations directly connected. Same settings as above apply.

io mux

Overview and configuration of input/output ports IO mux

1. Wireless relay WR-1 output function
On left side are WR-1 modules WR-1 (max 8) with corresponding status (active + communication status). To each WR-1 could be assigned HEMS function (e.g. digital, linker reset, router reset, heat pump channel etc) with output mode (normal or inverted).
2. HEMS input and output function (wired connection) - not for EVSE available
In column on the left side are MC controller (MC-230) ports to which could be assigned MC-230 functions (digital, linker reset, router reset, etc) with output mode (normal or inverted).
Default settings are for e.g. QX0 → digital 1 while digital 1 is defined for consumer 1 (settings page). It could be changed in a way to define new function role to QX0 port e.g. for linker reset
If it is selected Enable consumer at input IX0,IX1 or IX2 it means that dedicated consumer will be managed (ON/OFF) by input signal on IX0,IX1 or IX2. For example, thermostat signal is wired to IXO port and via IO mux defined “Enable consumer 1” to IX0. While thermostat is active, it is consumer 1 active as well and vice versa.
Limitations: one temperature sensor is allowed, one consumer could be managed by one input only
3. Heat pump supported operation mode
To control Heat pump by EVSE, define supported operation(control) mode based on heat pump specification. E.g. SGRHP supports external control by two channels (Off, Normal, Increased and Increased + additional heater) thus select them in table to enable functionality. Note: Before selecting modes, heat pump must be defined in setting page!
4. Slave device IP address
For device (PV inverter or external EVSE) define its IP address.
