Appendix 2: Trim Heater Control via Mercury/Intuitive Range
Energy savings via the RDM’s range of case controllers can be achieved in a number of ways. One of which is pulsing the trim heater
relay off for a given period of time. One way to pulse the trim heater is by configuring P-14. For greater energy savings the Data Manager
energy feature trim control or the Mercury Switch trim control feature can be used. These two options pulse the trim relay dependant on
the actual shop floor humidity levels. Thus if the shop floor humidity is relatively low the trim heaters can be pulsed off for longer
durations. Please see the relevant user guides for further details.
RDM recommend that the Trim Heater Pulse Module (PR0723) is used in all instances of trim control. This module is fitted in between the
trim heater of the case and the relay output of the Controller which is pulsing the heater. The trim heater module output provides a
smoother power distribution, compared to using the relay output directly, as it switches at the zero voltage crossover point. Switching the
trim heater on and off via a normal relay, without using the RDM trim heater pulse module, may damage the trim heater and reduce the
operational life of the heater. Therefore RDM recommend the use of this module in every trim heater control application. Please see the
Trim Heater Pulse Module user guide for further details.
