14.6 ALIGNMENT (HEAD) -
MENU > SETUP (PASSWORD) > PROFILE > EDIT SELECTED PROFILE > ALIGNMENT
Settings in this menu allow you to monitor alignment at the head and/or tail sections of your equipment.
Sensors are installed in pairs (left side - right side) at the head and/or tail sections.
• 14.6.A HEAD SENSOR PAIR
- This section allows you to enable or disable head alignment
monitoring. Four options are available:
1. OFF
2.
Pulsed
3. Contact (Default Setting)
4.
Rub Block
PULSED - Choose this option if using 4B WDA Motion Alignment Sensors, or Touchswiches that are
receiving pulses from a P800. The number of pulses detected by the sensors on the right and left
sides are compared. If the ratio between the two is less than 66%, an alarm condition is generated.
The value of 66% is fixed and cannot be altered by the user.
CONTACT (Default) - Choose this option if using 4B Touchswitch sensors (not receiving pulses
from a P800). In this mode, the Watchdog looks for a change in signal level representing the belt
alignment condition.
-
ON: +24V into the terminal is seen as Normal (no belt misalignment).
- OFF: 0V into the terminal is seen as a belt misalignment condition.
RUB BLOCK - Choose this option if using rub blocks to detect belt misalignment. A rub block
is basically a temperature sensor mounted to a special block (usually brass). If the belt rubs
constantly against the rub block, heat from friction will cause the rub block’s temperature to rise. If
the temperature rises above the preset limit, a misalignment alarm will be generated. There are a
number of settings available for use with the rub block.
• 14.6.B HEAD TRIGGER ALARM
- If CONTACT is selected within the HEAD SENSOR PAIR menu,
a trigger alarm must be selected. The default is OFF, meaning that an alarm will be triggered when
the contact is off (0V). If ON is selected, the alarm will be triggered when the contact is on (+24V),
this option (ON) is only available under FACTORY SETTINGS.
• 14.6.C ABSOLUTE ALARM [DEG]
- If RUB BLOCK is selected within the HEAD SENSOR PAIR
menu, an absolute temperature value must be selected. If the measured temperature of the rub
block exceeds this value, an alarm is generated. This level setting ranges from 32° to 230° F (1° to
110° C), the default is 140° F (60° C). For PRE ABS ALARM information, refer to section 14.4.B.
