5.14 Restart the iH system after emergency stop or automatic shut-down
WARNING
If a pump is automatically shut down, ensure that it is safe to restart before
you restart the pump.
Note: If the iH system has automatically shut down because of high HCDP pump power (alarms 412
and 512), check that the HCDP pump is free to rotate before you restart the iH system: refer to
Section 6.17.
If you have used the emergency stop switch on the dashboard to shut down the iH system,
you must reset the emergency stop switch before you can restart the iH system. Turn the
emergency stop switch to reset it, then restart the iH system as described in Section 5.6. Note
that the 'STOP ACTIVATED' alarm message (see Table 6-2) will stay on the Pump Display
Terminal until you restart the pumping system. See Section 5.17 for details of starting the
system if the disconnect box is fitted.
If the iH system has been automatically shut down because of an alarm condition, the alarm
condition must be rectified before you can restart the iH system. For example, if the iH
system has been shut down because the HCDP pump-body is too hot, the pump-body must
be allowed to cool before you can restart the iH system. Restart the iH system as described in
Section 5.6.
