Loop Pump Control (Former Pump Valve Relay Kit) - Bosch Greensource SM024 Installation, Operation And Maintenance Manual

Greensource CDi Series SM Model
6. A detection circuitry provides protection in
case of a faulty starting capacitor EMR. In such
situations, the red LED will flash four times for
five minutes. Smart Start Assist will check the
status of the starting capacitor EMR before
attempting a ramping function (in the case L/
L1 is closed). If at the second attempt, the
starting capacitor EMR is found to be faulty,
user intervention is required to reset the
controller by cycling power for the device.
7. In the case of incomplete ramping of the Smart
Start Assist, the red LED will flash five times.
The flashing will be indicated by the red LED
for five minutes. If after the second attempt,
there is another incomplete ramp alarm, user
intervention is required to reset the controller.
8. During the recovery from under-voltage,
overcurrent, and incomplete ramp alarms, the
red LED will flash twice the normal flashing
frequency using the same number of flashes.
Fig. 67 shows the flashing in case of a recovery
from an undervoltage alarm.
9. During the recovery time between starts, the
Smart Start Assist will be continuously ON until
the necessary recovery time elapses.
10. If Power supply on Smart Start Assist is
removed before the recovery period has
elapsed, when supply is restored, the delay will
continue until the remaining recovery time
from the last start/stop (before supply
removal) is over. Following this, another start
may be attempted. If supply is removed during
alarm recovery (red LED flashing), when supply
is restored, the alarm will be reset and the
Smart Start Assist will only wait for the
respective delays between starts and/or stop
to start to elapse before attempting another
start (assuming L/L1 is closed).
For Smart Start Assist troubleshooting
information, see page #54.

Loop Pump Control (former Pump Valve
Relay Kit)
A loop pump control relay has been integrated into
the HPC board. The loop pump control can be used
to energize a field-installed pump or solenoid valve
when there is a call for compressor operation. This
loop pump control relay is used to switch 208/240
VAC signals ON/OFF (depending on the supply
voltages).
NOTICE: The loop pump control relay output is
208/240 VAC at 5 A; ensure the pump or valve
being connected is rated to this specification.
