−Warnings & Cautions
Cautions
Power to sensors is provided at TB2
−
6 (+12 Vdc) and TB2
−
5 (common) on the TR400. Wiring
to those inputs should be shielded cable with the shield tied to TB2
−
5 common only. Failure to
observe this caution could result in improper sensor function.
Always turn the power source OFF before wiring the TR400. Failure to observe this caution
could result in damage to the TR400.
Never use shielded cable
U
with extra conductors
U
. Extra conductors can act as antennas, picking
up electrical noise. Failure to observe this caution could result in improper sensor operation.
The TR400 standard uses 115 Vac, 6 VA @ 60/50 Hz, with 230 Vac as an option. Make sure
you know the correct supply voltage before applying power to the TR400. Failure to observe
this caution could result in damage to the TR400.
Do not touch the Pulser Disc or Wrap while it is spinning. Failure to observe this caution could
cause an interruption in pulse generation, resulting in a disruption in the mechanical process
being monitored.
When the digital input function is programmed as a Reset input and the switch input remains
closed, the relay will never turn OFF regardless of the operating condition. A momentary
contact closure of the switch is advised. Failure to observe this caution could result in damage
to the equipment.
Only qualified personnel should attempt to connect any wires to the TR400. Failure to observe
this warning could result in damage to the equipment.
