7.11.2.1
Steps for setting the control parameters for external control
1. Activate external control
Ö
2. Setting the slave controller:
2.1. Set parameters to
auto
; Check for thermostat type and change when necessary (RP....)
Ö
−
Choose heat transfer liquid with low viscosity and high thermal capacity.
Ranking: water, ethanol, water-glycol, oil, Fluorinert®.
−
Set pump level as high as possible,
−
make bath circulation strong and fast,
−
choose hose length as short as possible, i.e. 2 x 1m,
−
choose hose cross section as large as possible, i.e. ½ inch,
−
throughput through the external load as large as possible.
2.2. Xpf setting:
−
when oscillating with short period occur (i.e. 30 seconds)
Î
Xpf lower, otherwise higher,
−
in case of bad thermal coupling and large thermal mass
Î
high (i.e. 2...5, or even higher),
−
in case of good thermal coupling and small thermal mass
Î
low (i.e. 0.2 ... 0.7),
−
when rapid temperature response is required simple internal control should be preferred.
Otherwise select small Xpf (0.05 ... 0.1).
3. Setting the master controller (PIDT1-controller):
−
Start with setting Auto and proceed with Manual only when necessary.
