5. Update - JETI model Main Switch 200 ex User Manual

User Manual: Electronic switch Main Switch
MENU: ALARMS – setting of individual alarms.
If one of the adjusted parameters becomes exceeded, the JETIBOX LCD will in the second line of the basic
menu alternately show the original display with the pertinent alarm and the transmitter module siren will emit
an acoustic alarm. The first tone is a revelation signal and the second one is signaling a Morse code character
of the relevant alarm. If the alarm is set to OFF, this kind of alarm will be switched off.
Voltage Alarm (alarm U ..- ) – adjustment of the value of voltage signaling. If the measured voltage
decreases beyond the set value, the voltage alarm U will be activated.
Current Alarm (alarm I .. ) – adjustment of the value of current signaling. If the measured current increases
beyond the set value, the current alarm I will be activated.
Capacity Alarm (alarm C -.-. ) – adjustment of the signaling value of consumed capacity. If the adjusted
value of maximum consumed capacity is exceeded, alarm C will be activated.
MENU: SERVICE – by pressing button D (arrow down) you will change the display to show the firmware
version and to renewal of the switch default setting.
Factory Defaults – by simultaneous pressing of arrows R and L (right and left) the factory settings of the Main
Switch are loaded.
M200 v. xx.xx ID xxxxx:xxxxx – product marking with firmware version and series number (ID).
Fig. 4: Phases of current measurement
C – the set current has been exceeded and the current alarm has been activated.
D – the measured current decreased beyond the set alarm value, alarm will be cut off. The measured current
decreased beyond the set level Start Trigger. The timer Run Time is switched off. Recording of extremes and
consumed capacity continuous.

5. Update

The Main Switch allows updating of its firmware via PC. Updating is done using the JETI USB adapter.
◦ Connect the USB adapter to the RC Switch (Ext. output) using a three-wire cable.
◦ After connecting the device the update will begin. Procedure:
measurement course.
Particular phases of current measurement
A – when after switching on the current did not exceed the set
value Start Trigger. Measured values (U MIN / MAX, I AVG /
MAX, Capacity, Run Time) correspond with measured values of
the previous operation.
B – the value Start Trigger has been exceeded.
Previous measured values (U MIN / MAX, I AVG / MAX,
Capacity, Run Time) will be deleted and actualized by the actual
