2.2 Interface Description
2.2.1 Power Supply
The system is designed to support off-road mobile applications on 12 VDC and 24 VDC systems.
Table 1: Power Supply Characteristics
INPUT VOLTAGE 6-32 VDC
INPUT CURRENT Less than 300 mA at 12 VDC
Less than 175 mA at 24 VDC
PROTECTION - Reverse polarity
- Load dumps and electrical transients
2.2.2 Safety Relays
The CCM12 has two independent safety relays; each relay is controlled by one processor, and monitored by
both of them, as shown:
Figure 6: Safety Relays interface block diagram
Contacts for the relays normally-open are connected to the CCM12 main connector, while the normally-closed are
used for relay monitoring.
The safety relays main contacts (normally-opened) are closed when a valid RF connection is established from the
OCU, and the MCU is operating without error. Since the master and slave processors run parallel operation, both
relays operate quasi-simultaneously.
It is recommended that the contacts for both relays be connected in series to the machine E-STOP circuitry.
