The complete electrical control schematic for automatic start and stop of the SDMO APM303 generator includes:
1. Generating Set – The main generator unit. 2. APM303 Control Module – Manages generator operations. 3. CAN Display – Optional, depending on motor type. 4. Manually Controlled Circuit Breaker – Connects or disconnects the load. 5. Automatic Transfer Switch (ATS) – Automatically switches between the generator and the electrical network. 6. Electrical Network – Main utility power supply. 7. 2-Wire Remote Start Connection – Between the ATS and the generator for sending automatic start/stop signals. 8. Voltage Measurement via K6 Connector – Terminals 20 (N), 21 (L1), 22 (L2), 23 (L3) for 3-phase connection. 9. AUTO Mode on APM303 – Enables automatic control based on remote start signals; press AUTO button to activate.
In AUTO mode, the APM303 automatically starts and stops the generator based on mains power availability detected by the ATS. The ATS monitors the mains and sends start/stop signals through the 2-wire connection.

The "user level" user manual is designed for users who are qualified to set up an installation (generating set and environment). These users must be able to monitor that the generating set is operating correctly (start, stop, basic settings), to interpret any indications (mechanical, electrical) and may be required to check one or more parameters. The "operator level" user manual is designed for those who – in addition to the skills required for users ...

To do this, the operator will have completed training provided by SDMO Industries beforehand. Note: for the APM303, no distinction is made between the user and the operator. This means that a user can modify all the internal parameters (no access code in the APM303).
0/1 switch, located on the front of the central console. On powering up, the APM303 automatically runs in the operating mode which was pre-set before it was switched on (see section ‘Selecting the operating mode’).
When MANU mode is selected ( AUTO LED off), if there is a remote start order (activation of the "remote start/stop" input, nothing happens, the APM303 remains in MANU mode, but the AUTO LED flashes to signal that there is a remote order.
This input must be a potential-free contact ( ), this means that the user must not connect an external power supply to the terminals provide for this purpose. This will destroy the APM303. ( ) In general, the external input comes from an automatically controlled ATS.
Display of data To view the data measured and recorded by the APM303, the user has 6 or 7 screens available: - 7 screens are automatically displayed one after the other, with a delay of 7 seconds, - 6 screens are displayed by successively pressing the...
(e.g.: 10). Figure 8 - meters Events and anomalies, screen 6 Screen 6 shows the list of events and anomalies recorded by the APM303 . A maximum of 12 events and anomalies can be recorded (the last 4 appear on screen).
Events and anomalies Events An event is either a change in APM303 status (powering up), or activation of one the 3 buttons, or any change in the PLC status (e.g. start-up). The table below lists all the events which can be recorded in the stack.
3 minutes. This symbol also appears if there is a charging alternator malfunction. Flat battery: if the APM303 cannot start up the generating set (because the battery voltage is too low), this alarm will be activated, but the starting sequence is not blocked.
2 rpm, or if the voltage exceeds 10V, or if the oil pressure remains higher than 3Bar, or if the generating set is started up when no start demand has been given by the APM303. The safety feature is taken into account after fixed delay of 60 seconds.
(see user/operator level manual - configuration software). Accessing settings (Main menu) The settings can only be accessed if the APM303 is in Manual mode. Access to the settings varies according to whether or not the home screen is displayed.
