• IM-P403-89 EMM Issue 8 49 6.4.10 ALARM sub-menu An alarm is triggered at a set PV figure (TDS / conductivity). Hysteresis – 3% (default), 0 – 100% FS, 0.1% resolution. Prevents over-frequent switching of the alarm in a turbulent boiler. Do not set to more than 15% unless exceptional operating conditions are present. A further damping effect for very turbulent boilers (0 — 99s). Only available if timer switch is fitted and selected. Bottom blowdown alarm. In the ON position, an alarm will occur

• IM-P403-89 EMM Issue 8 47 An automatic probe scale detect feature is available if a CP32 two-tip probe is fitted and selected. It selects the action taken by the controller to a probe with too high a resistance, caused, for example, by scaling. If ‘CLEAN’ or ‘AL + CLEAN’ is selected, the interval time is automatically set to 10 minutes until the scale is removed – see Figure 32. Constant Pulsed Fig. 32 Duration 10 minutes OUTPUT RETRANS notes This sets the controller outputs to suit the two current loop standards in common use. It retrans
