DESCRIPTION The models 1022 and 1025 are single-phase phase-angle SCR power controllers. The controllers are the same except the 1022 accepts command signals of 0/5Vdc, 0/10Vdc or a potentiometer signal. The model 1025 accepts a 4/20mA command signal. Both controllers control the RMS voltage to the load proportional to the command signal, independent of line voltage hanges.

ZERO AND SPAN ADJUSTMENTS The zero and span adjustments have been factory adjusted to provide zero load voltage when the minimum command signal is applied and to provide rated output voltage to the load when the maximum command signal is applied. Further adjustment of these settings should not be required. If it is desired to readjust the zero and span settings the following procedures should be followed.
TROUBLE SHOOTING CAUTION: High voltage exists on the supply and load terminals of this controller and may exist on other equipment located near the controller. Use extreme caution to avoid electrical shock. The LED located on the controller circuit can be used to aid in determining problems. This LED varies in intensity proportional to the command signal and therefore should be proportional to the load voltage.
MODEL NUMBER IDENTIFICATION 102X-VV-AA [-SCXXX] [-MOXX] X = 2 for 1022, 5 for 1025 1022 (0/5Vdc, 0/10Vdc or POT control) 1025 (4/20mA input) VV = Rated voltage: 12 = 120Vac 24 = 240Vac 48 = 480Vac 57 = 570Vac AA = Rated amps: 10, 20, 30, 40, or 70 amps Note: The addition of "-SCXXX" implies that the controller has been modified to have a different input command. For example, a "-SC1/5Vdc" implies the controller has been modified to operate with a 1/5Vdc control signal.
