SH6- HEATER CONTROLLER SERIES
Before turning on power to the drive confirm that the voltage
rating of the drive is the same as that of the 3 phase input
supply.
SH6-XX-3 - 380V SUPPLY
SH6-XX-5 - 525V SUPPLY
Check the LK1 on PC550 is set to the correct input voltage.
If there are any problems during start up refer to Section 5 -
Trouble Shooting, for assistance.
4.2.1 SH6-100-X THROUGH SH6-800-X
This range of heater elements use the current control
method. Two current transformers are used to provide
current feedback to the PC550 control card. The burden
resistor DIP Switches on the PC550/7 card is selected so
that the current drawn by the load can be limited to a
max of 100% of FLC. See Table 4.1 - Current Burdens.
(Value 1 must be in parallel with Value 2).
