EXTERNAL CONNECTION DIAGRAM OF UNIT Connection diagram for each setting system Connection diagrams for each setting system are shown below. Short circuit between GT and PH terminals during operation. Open-circuiting between them during operation forcibly stops output. Short-circuiting between ST and PH terminals starts output, and open-circuiting between them stops output. -
Page 11: How To Connect Unit Control Cables
How to connect unit control cables Use an easy lock to bind up the control cables (for control power supply, major failure output, minor fail- ure output, external input and output terminals, and conversion board) of the unit. Fix the easy locks on the unit. Bind the control cables with the easy locks. -
Page 12: How To Set Unit
HOW TO SET UNIT CAUTION Perform a setting of the unit with a good attention in that live parts are exposed when opening a cover of the unit. Before setting, turn off power. The standard initial setting of this unit is as listed below. If the unit is used under other conditions, open a cover on the lower part of the unit to change the setting of dip switch S1 located on the printed circuit. -
Page 13: Setting Of Dip Switch S3
Control system (S1-1) [Function] This makes a selection of phase control or cycle control. The phase control is to control the phase of half-cycle by means of its effective value. The cycle control is to control the number of turning ON in one cycle during a certain con- stant period by means of its effective value. -

Page 15: Detection Of Abnormality
DETECTION OF ABNORMALITY Detection and indication of abnormality CAUTION In the event of any abnormality, check the Unit Abnormality lamp, stop operation of the unit, and then turn off power. When an abnormality detection circuit functions, an abnormality indication lamps lights up or flickers on the right-hand side of the terminal block inside the front panel of the unit. - Page 16 This detects fuse disconnection when a fuse built in the unit is disconnected. On detection of fuse dis- connection, an “F” indication lights up and operation stops. To resume operation, turn off the control power supply. The optional function is provided to detect heater disconnection. On detection of heater disconnection, an “HET”...

Without conversion With conversion Operating status after board board detection of abnormality In running In stopping In running In stopping Thyristor open Available Operation stops. -
Page 18: External Warning Circuit
External warning circuit The abnormality detection circuit, when activates, causes an external warning relay in the unit to acti- vate. Major and minor failure relays are provided as the external warning relay. Major failure relay The abnormalities described below, when detected, forcibly stops operation and at the same time causes a major failure relay in the unit to activate. -
