LCD Hour Meter
•
High Voltage DC or AC – Low is less than 3VDC or 3VAC. A High Input is either 10 – 300VDC or 20-300VAC.
For the Switch and Low Voltage DC Hour Meters, there are six screw terminals for all of the I/O. For the High Voltage Hour Meters, there are four screw
terminals for the I/O. The combinations of the I/O and power supply are factory set.
Enable Inputs:
The enable inputs are those inputs that enable the accumulation of time.
Remote Reset:
When the remote reset is at a high level, the Hour Meter will reset.
Front Panel Reset Enable:
The Hour Meter will reset when the Front Panel Reset Enable is at a high level, and the Front Panel Reset Switch is
pressed. The Hour Meter will not reset when the Front Panel Reset Enable is at a low level and the Front Panel Reset
Switch is pressed.
Output:
The output is an open-drain MOSFET. The output is used when operating in the Preset Mode, and it can be optionally
used when using Redi-Alerts.
Preset Function
Each Hour Meter may be placed in a preset operating mode. This mode can be programmed through the front panel for those units that have the front
panel programming option. It may also be factory programmed. IT IS NOT RECOMMENDED THAT THE PRESET FUNCTION BE USED AT THE SAME
TIME THAT ALERTS ARE ENABLED.
Basically, a preset Hour Meter is an Hour Meter that times to a preset value and then turns on an output device. At some point, the output device is
turned off, the Hour Meter is reset, and the process begins again. There are two things to determine. One is when and how to turn off the output device,
and the second is when and how to reset the Hour Meter.
The preset Hour Meters can be set up for either automatic reset or external (front panel or remote) reset. The outputs can be turned off by either time
out or external reset. In addition to the output, an icon can be turned on when the output is turned on for a visual indication of the preset condition.
Alert Functions
The Model 63 Hour Meter can be programmed to operate as a maintenance device in which alerts notify the user of certain maintenance actions to be
taken after accumulation of a predefined time. When the accumulated time equals the predefined alert value, an icon is illuminated on the display. When
the alert is reset, the icon is turned off, but the accumulated time is not reset.
There are two types of alerts. The first is a break-in alert. A break-in alert only occurs once at the start of unit operation. The second type of alert is
recurring. A recurring alert occurs continuously at a predefined period. When tied to a break-in alert, the recurring alert will not begin its count until the
break-in alert has occurred.
The intervals for the recurring alert can be performed as start-to-start or end-to-start. A start-to-start interval count starts when the last alert is turned on.
The end-to-start interval count starts when the last alert is turned off.
The Model 63 Hour Meter can support three alerts using front panel programming and four alerts when factory programmed. IT IS NOT RECOMMEDED
THAT THE PRESET FUNCTION BE USED AT THE SAME TIME THAT ALERTS ARE ENABLED. In both cases, Alert #1 is a break-in alert that is tied to
Alert #2, which is recurring. Alert #3 is recurring, and Alert #4 can be factory set as either break-in or recurring. If Alert #4 is break-in, then it is tied to
Alert #3.
The Model 63 Hour Meter can be programmed to be latched or kept on for a predetermined time. When latched, an external reset is required to turn off
the alert. Each alert can also force the output on when the alert is on.
Front Panel
The liquid crystal display is reflective with dark characters on a light background. There are 8 digits on the display. The standard display contains seven
icons which can be assigned as desired to either alerts or a preset.
Model 63 Hour Meters with the front panel programming option are capable of being programmed for either alerts or the preset function. There are two
front panel switches. To begin programming, the two switches are pressed simultaneously. The programming menu must be completed in its entirety to
return to normal operation. The switch functions are described as follows:
SEL:
During normal operation, the displayed Hour Meters will be swapped when the SEL switch is pressed and released. During programming, this
switch is used to select options.
RST:
During normal operation, the RST switch is used for front panel reset. During programming, the RST switch is used to enter an option.
Resets
Unless using alerts, a reset returns the display to zero. If using alerts, the reset turns an alert off. There are three different reset configurations available:
Non-Reset:
The Hour Meter can never be reset. A non-reset unit also has no front panel programming option.
Remote Reset:
A model with Remote reset has a dedicated terminal for performing the reset function. The unit resets when the remote reset signal
is at a high level. When the reset signal is at a low level, accumulating time can occur.
Manual Reset:
Manual reset occurs when the RST switch on the front of the Hour Meter is pressed. Accumulating time resumes upon release of
the RST switch. The exception to this operation is in the Dual Hour Meter case; the non-resettable Hour Meter can not be reset.
Note: Some Hour Meters are equipped with a Manual Reset Enable Input. In this case, the Manual Reset Enable Input must be high for the RST switch
to be functional.
