Lowering The Warm-Up Temperature; Disabling The Warm-Up Cycle; Increasing The Warm-Up Temperature; Stop The Pump Going On-Process When It Is Warm - Edwards GXS Series Instruction Manual

9.6.1 Lowering the warm-up temperature

Use the warmup setpoint temp menu item and decrease the warm‑up set point to the
desired temperature. The minimum temperature allowed is 0 °C.

9.6.2 Disabling the warm-up cycle

It may be required for the pump to skip the warm‑up cycle and go directly on‑process
once it has reached full speed. There are two ways to achieve this:
▪ Enable COLD ONPROCESS
▪ Adjust the WARMUP Setpoint temp set point to below ambient temperature.

9.6.3 Increasing the warm-up temperature

Use the Warmup setpoint temp menu item and increase the warm‑up set point to the
desired temperature to suit your application.
Note:
The maximum temperature allowed for warmup setpoint temperature is above the
alarm limit for the pump so if the temperature is set too high the pump will never
‑ up. Changing the warm ‑ up temperature does not change the pump's water
warm
cooling operation. This is fixed by us and can only be changed by a downloadable
configuration.

9.6.4 Stop the pump going on-process when it is warm

The pump can be configured to automatically go into the Green mode/standby mode
when it is warm instead of going on‑process. To do this, go to auto Green Mode menu
and disable auto Green Mode.
Note:
If the pump is controlled by a tool interface then the pump will follow the state of the
‑ process line.

9.6.5 Stop the pump automatically warming up when in Green mode/standby
mode
If the pump is running in the Green mode/standby mode and its internal temperature
drops below the warm‑up set point then by default the pump will automatically perform
a warm‑up cycle. This could result in the pump speeding up and slowing down over a
period of time.
If the application does not require the pump to remain above the warm‑up set point
while in the Green mode/standby mode then automatic re‑warming can be disabled
using the Warmup auto rewarm menu item.

9.6.6 Turn the inlet purge on during warm-up

A pump can be made to warm‑up more quickly by adding inlet purge during the warm
up cycle. This is enabled using the Inlet purge menu item.
