Edwards nXR60i User Manual

Note:
The s
top command does not isolate the pump from the electrical supply.
Standby
In standby mode the pump operates at a reduced speed to improve the service life of
the pump.
1. Push the standby buon to select standby mode. The pump will inially run at
factory default standby speed (70% of full speed).
2. Adjust the speed with the increase and decrease standby speed buons. The
maximum standby speed is 100% of the default run speed and the minimum
standby speed is 50% of the default run speed.
A single short push will change the speed by 1% of the default run speed. Hold the
buon to change the speed by 1% per second.
3. Once adjusted, the pump will return to the new user dened speed each me
standby speed is selected.
4. Push the standby buon to return to normal run speed.
So start and so stop modes
For most pumps operang under normal laboratory condions or at ulmate pressure
the so-stop mode or so-start mode is unlikely to be invoked.
So stop:
If the pump is operang within a high ambient temperature the product may enter a
so-stop mode when the o command is sent or stop buon is pressed, this protects
the product mechanism during the shutdown procedure by enabling the pump to relax
back into its stopped state. The so-stop mode is likely to be acvated in ambient
temperatures higher than 30 °C. During the so-stop mode the pump speed is halved
and the cooling fan speed is increased to enable controlled cooling of the mechanism.
Once a pre-dened temperature level has been met the pump will switch o completely
and is then ready for restart.
The so-stop cool down me period is expected to be < 1 minute in the majority of
cases, but could last up to 4minutes depending upon the ambient temperature and load
applied to the pump.
Once the so-stop process has been acvated the pump cannot be restarted unl the
shutdown is complete.
So start:
If the internal pump temperature is above a pre-dened threshold, the pump can not
start immediately, when the start command is sent or start buon is pressed. Instead,
the cooling fan will switch on at full speed to cool the pump and once temperatures are
suciently low the pump will run up to full speed as normal. The delay to start is
expected to be < 1 minute in the majority of cases but may last longer depending upon
the ambient temperature of the cooling air and the inial temperature of the pump
module.
