Page 12: Periodic Cleaning
PERIODIC CLEANING Every 6-12 months (depending on the dust level of the installation) blow a compressed air jet downward through the upper rectangular cooling grilles (on the side opposite the fan). This will clean the internal heat dissipater and the cooling fan. IN CASE OF OVERHEAT ALARM ATTENTION: Before and during the inspection/maintenance cut power to the fan controller and verify that the system is... -

Page 18: Burst Firing Mode
Firing modes The IR24- IR12 power controllers have the following control modes: - modulation by variation of phase angle - modulation by variation of number of conduction cycles with “zero crossing”, Burst Firing or Half Single Cycle firing Burst Firing mode BF -with variable cycle time This mode manages power on the load by means of a series of conduction (ON) and non-conduction (OFF) cycles. -
Page 19: Additional Functions
4 Phase angle (PA) This mode controls power on the load via modulation of trigger angle q Example: if power to be transferred to the load is 100%, q = 180° if power to be transferred to the load is 50%, q = 90° Figure 13 Inductive load Resistive load... - Page 20 It is positively identified by means of a node address (ID) set on rotary switches (tens + units).
