1.
Ensure that Wet/Dry Input Type switch is set to
DRY
before applying power to the RTT
unit.
After connections are made, switch to
WET
2.
Ensure that current and voltage knobs are turned fully counter-clockwise before
applying power to the RTT unit.
Note
Wherever a "tilde" (~) symbol appears, substitute the slot position of the module.
*Contact Output Common terminals (~3b and ~4b) must be hardwired together.
**The voltage threshold of Contact Input should be programmed as 17 VDC.
**Contact Input Common terminals (~5b and ~7b) must be hardwired together.
