Var08.
Underspeed_Start_Delay_Time.
This is the number of seconds to wait after an
Hour_and_Speed_Enable command has been given, before
enabling speed monitoring.
Var08
range is 0000 to 0030 seconds.
Factory default for Var08 is
0005 seconds.
Var09.
Speed_Display_Select.
Show speed in % or RPM on the 4-digit LED Speed Display, and
Enable/Disable Speed Alarm Monitoring.
The
Var09
range is limited to the display selections listed below:
Var09

Factory default for Var09 is 0000 for speed in ‘%’ and Speed
Alarm Monitoring enabled.
Var10.
MAX_ANALOG_RPM.
When
Var01
=0000 for 4-20mA analog encoder type, then
Var10
MAX_ANALOG_RPM is the maximum RPM seen by the
4-20mA encoder in the application.
Note:
Var10
is meant to be used when the application’s
maximum speed is less than the analog speed encoder’s
rated 20mA RPM (i.e. a
Var10
less than
Var03
).
Var10
range is 0000 to 9999 RPM.
Factory default for Var10 is 0200 RPM.
Note: If
Var01
is set for Pulse-Train encoder type, then
Var10
is
irrelevent and it’s value is ignored.

Var11
allows the Analog Inputs #’s 3, 4, 7, 8, 11, and 12, to be
programmed for either 4-20mA Temperature type sensors or for
Contact-Closure type sensors. Rub Block sensors are always
expected to be operated in pairs and are horizontally across from
each other on the ES1’s Front-Panel.
Var11
range is 0000 to 1111, with only
0
’s and
1
’s allowed.
The left-most-digit programs the Contact-Closure’s Sensor Logic.
The three-right-most-digits program the Analog Input pair’s
Sensor Type.

Sensor Logic:
0 = Open ckt is “SAFE”, Closed ckt = Alarm
1 = Closed ckt is “SAFE”, Open ckt = Alarm
·
Left-most-digit = ‘0’: programs the normally ‘Open-circuit’
case as the ‘non-alarm’ Green zone state, and the Contact-
Closure’s ‘Closed -circuit’ case as the ‘Yellow_Alarm’ state.
·
Left-most-digit = ‘1’: programs the normally ‘Closed-circuit’
case as the ‘non-alarm’ Green zone state, and the Contact-
Closure’s ‘Open-circuit’ case as the ‘Yellow_Alarm’ state.
Factory default for Var11 is 0000, for all Analog Inputs are set
for 4-20 mA temperature sensors.
Notes for
Var11
:
·
When a Contact-Closure sensor gives an alarm it is a ‘Yellow_
Alarm’ only (i.e., no ‘Red_Alarm’ for a Contact-Closure).
·
When a Contact-Closure sensor ‘alarms’, it alarms with
the corresponding 3-digit display’s discrete Yellow-LED /
Yellow-Lightstack-Relay / Speed-Temperature-Warning-Relay
/ Horn-Relay, and the 3-digit LED display shows ‘ALr’. If
the Contact-Closure sensor were to return to the Green zone
‘non-alarm’ state, then the ‘Yellow_Alarm’ remains ‘latched’,
with the 3-digit LED display remaining at ‘ALr’. Once the
Contact-Closure sensor has returned to the Green zone ‘non-
alarm’ state, then to ‘clear’ the latched ‘Yellow_Alarm’ the user
must give a ‘Silence_Horn/Alarm_RESET’ command to the
ES1. (See Operating Note section “How to Clear Alarms” for
details.)
