Connect to proper source voltage
Verify source voltage before applying power. The "Pin Assignment" side label indicates the input power required for each model and indicates either Fail Safe operation
or Fail Secure operation.

Rear Panel DIP Switches and Rotary Switch
2-Position DIP Switch – Loop Frequency
SWITCH

Loop Frequency (DIPS 1 & 2) is controlled by the rear panel 2-Position DIP switch. On occasion, loops are placed in close proximity; it is necessary to select a different
frequency level for each loop to avoid loop interference (crosstalk). Four (4) frequencies are selectable, HIGH being the factory default. Press reset after changing sensitivity
setting.
