Inputs And Controls - Prime DS101 Operating Instructions Manual

4. Always use shielded cable from the probe to the control module (Belden 8771 or equivalent).
The probe is connected to terminals on the rightmost terminal block labeled Red, White,
Black & Shield. Connect the shield leads (drain wires) from the probe cables to the terminals
labeled SHLD. If a splice is made between the control and probe leave the probe unshielded
no more than 20 to 30 mm.
5. The output relay may be operated in a "follower" mode or "memory" (latch or sealed) mode
depending upon the wiring of the RESET input. The mode connections and definitions are
described below.
a) To operate the output in the "follower" mode, jumper RESET and COM. together on the
terminal block. When a DOUBLE condition occurs, the relay drops out and the DOUBLE
indicator comes on. When the double metal condition is removed, the relay returns to the
normally energized condition, the yellow DOUBLE indicator goes out and the green NO
DOUBLE indicator turns on. Automatic reset is normally selected to control the operation
when the fault condition is automatically removed or the DS101 is wired into the stop circuit
of a machine with a manual restart circuit.
b) To operate the output in a "latch" mode, wire the RESET and its associated COM terminal to
the normally open contact of a switch, relay, or controller output. In this mode, when a fault
condition occurs, the relay drops out and the DOUBLE indicator comes on. After the fault
condition is corrected, the RESET contact must be momentarily activated to bring the relay
back to the NO DOUBLE state.

INPUTS AND CONTROLS

The primary control input to the DS101 is the calibration push-button switch on the front panel.
Use of this switch is described below under CALIBRATION.
The DS101 has two logic inputs labeled CAL and RESET. The CAL input parallels the function
of the calibrate push-button on the front panel allowing the calibration function to be performed
through a remotely located switch wired to this input. The RESET input controls the latching of
the relays as described in item 5 of the Electrical Wiring section above.
The two logic inputs have associated with them two jumper plugs located immediately behind
its associated terminal. The function of these jumpers is described below under
CONFIGURATION SWITCHES AND JUMPERS.
Both the CAL and RESET inputs are ON when pulled low (zero volts) independent of the jumper
settings.
