6.2 Electrical Interfaces
6.2.1 Control Signals
6.2.1.1 Table 3.1 specifies the required TMP control signals. In cases where TMP are backed up by battery or
regeneration power while input power failure, the status of output signals follows Table 3.2. Table 4 and Figure 3
specify the required response time for TMP control signals. Table 5 specifies the required power and contacts for
TMP control signals. Tables 6 and 7 and Figure 4 specify the required connector and pin assignments for TMP
control signals.
Table 3.1 I/O Signals
No. Signal Name Direction Type Remarks
1 Start (Run)/Stop Input signal to Pump Alternate Pump runs when
closed
2 Acceleration Output signal from Pump Alternate Close during
acceleration
3 Normal operation Output signal from Pump Alternate Close during normal
operation
4 Deceleration Output signal from Pump Alternate Close during
deceleration
5 Remote/Local Output signal from Pump Alternate Close during remote
operation
6 Pump Alarm Output signal from Pump Alternate Open at alarm
Running status signals
When input power is OFF, output
status signals should become open
(normally open).
