9.11.6 Test the PID control
1. If the booster is under manual control, ensure that it is switched on and running.
2.
Turn the Green mode o from the Command menu.
3. PID should now start automacally. If it does not start to control the inlet pressure
use the PDT and go to: Setup/Command/PID/On.
9.11.7 Auto tune the PID
The PID auto tune should not be used.
9.11.8 Manually tuning the PID
Use the following default PID parameters:
Tc = 1
Kc = 0.01 (increasing the value results in a faster me to target pressure. 0.02 is generally
the largest value required)
Ti = 50 (decreasing the value results in a faster me to target pressure. 20 is generally
the smallest value required)
Td = 0.0001
Do not change Tc or Td
PID parameters are accessed using the PDT ‑ go to Setup/Set sequences/PID/PID
parameters.
9.11.9 Turning PID on and o when on-process
The MCM MicroTIM or the PDT can be used to turn the PID on and o when the pump is
on‑process by conguring the PID to manual operang mode. This can be useful when a
pump down to base pressure is required before pressure control is iniated.
1. From the PID menu, select Operang mode...
2. From the Operang mode menu, select Manual.
Refer to the MCM MicroTIM manual and How to set up the MCM MicroTIM using the
PDT on page 156 for the informaon about using the MCM MicroTIM to enable PID.
9.12 How to set up the Ethernet port
The pump has a single 10 baseT Ethernet port that can be congured in either stac
address mode or DHCP mode. There are a variety of protocols that can be run over the
Ethernet port including FabWorks EtherNim, SIM and E54 Modbus.
The SIM protocol is the only protocol available for users. The manual for the SIM
protocol is P41100200. If the Ethernet port is to be used with dierent protocols then
contact us.
Before the Ethernet connecon is used, it requires a valid IP address. Set the IP address
using the PDT. Both stac IP addressing and DHCP dynamic addressing are supported by
the pumps.
