Note t
| A voltage of 12.17 V is currently set at the factory for undervoltage shutoff. This setting is active with code “00XX1” and can be altered by way of the “Adaption” function → Chapter. |
t
| Code “00XX2” is intended for an auxiliary heater version as supplementary heater to be introduced at a later date (with no circulation pump -V55-) and is not to be used for vehicles with auxiliary heater. |
t
| Depending on the version of the auxiliary heater control unit -J364- and the last active setting “Auxiliary heater” or “Supplementary heater”, the type of undervoltage shutoff active in this setting is displayed with code “00XX1”. The corresponding voltage value can be seen in display zone “3”. |
t
| As code “00XX2” is only intended for vehicles with supplementary heater with no auxiliary heater, a voltage of 9.5 V is set at the factory. However, in view of the fact that the supplementary heater is only switched on when the engine is running, the shutoff voltage is of secondary importance with regard to supplementary heating. |
t
| If the code “00XX2” is entered during service work for vehicles with auxiliary heater, the shutoff voltage envisaged by the manufacturer for this code must be set by way of the “Adaption” function to 11.30 V or above so as not to jeopardise reliable starting of the engine. |
t
| On starting, the shutoff voltage displayed in zone “3” is not active with code “00XX1”. The auxiliary heater is only switched off in the starting phase if the voltage is less than 9.5 V. |
t
| If the voltage value displayed is not reached for a specific period, undervoltage shutoff is implemented → Chapter. |
