7.11.2.1 Steps for setting the control parameters for external control
1. Activate external control Ö 7.5.4.
2. Setting the slave controller:
2.1. Set parameters to auto ; Check for thermostat type and change when necessary (RP....) Ö 9.1.1.
− 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.
