Electro-Sensors Electry-Sentry 1, Руководство по установке и эксплуатации

Страница: 4 / 32

Here are the basic questions/steps the user needs to
perform to get the Electro-Sentry 1 (a.k.a. ES1) up
and running:
1) What is the application’s voltage? 115 or 230 Vac?
VAC SW1 Position Fuse F12 Notes:
115 Towards Right 115Vac/0.4Amp
Slo-Blo
Factory Setting
230 Towards Left 230Vac/0.2Amp
Slo-Blo User Selectable
(The ES1 is shipped with one 230Vac/0.2 Amp Slo-Blo fuse,
and one extra 115Vac/0.4 Amp Slo-Blo fuse).
2) Do you need to display speed, or need Speed Alarm
Monitoring?
A) NO, Speed Display/Alarm Monitoring is not needed:
 Skip User Variables
Var01
through
Var08
.
 Skip the setting of the
SW9
3-DIP Switch.
 Set
Var09
Speed_Display_Select to either a ‘0002’
or a ‘0003’ to disable Speed Monitoring, as needed.
 Skip
Var10
MAX_ANALOG_RPM.
 Skip
Var34
Hour_and_Speed_Command_Select for
now. [If you plan to use the Hour Meter feature, we
will return to
Var34
later in section (5) below].
B) YES, Speed Alarm Monitoring and/or Speed
Display is needed:
 What type of Speed encoder are you using? A 4-20
mA Analog encoder or a Pulse-Train encoder?
 Set Var01 Encoder_Type_Select, as needed:
‘
0000’ = 4-20 mA Analog Speed Encoder Type
(speed signal is received at
TB16
).
‘0001’ = Pulse-Train Speed Encoder Type
(speed signal is received at
TB30
).
When Var01 = 0001, then you need to set
the
SW9
3-DIP Switch for NPN or PNP/
5V logic-level Encoder Type, as needed
per your pulse-train encoder. The SW9
DIP switch is on the back side of the Front
Panel, to the left of the J7 ribbon cable.
The Factory default setting of SW9 is for
an NPN Pulse-Train Encoder (which is
SW9’s switch #1 = ON, switch #2 = OFF,
switch #3 = OFF).
Note: Electro-Sensors Pulse-Train
Encoders are NPN encoders.

0000 = 4-20mA Analog Encoder.
0001 = Pulse-Train Encoder.

For applications using a
4-20 mA Analog Speed
Encoder
(i.e.,
Var01
= 0000):
Set the following variables as needed:

Var03
RPM_at_20mA.
This is the analog encoder’s rated
RPM corresponding to 20mA.
(See Note
2 ).
0200
RPM
Var10 MAX_ANALOG_RPM.
This is the peak RPM seen by the
analog encoder in the application,
and the 100% RPM on which the
speed setpts are based.
0200
RPM
Var04 Speed_Slowdown_Alarm_
SetPt %. (See Note
3
).
This is the ‘Yellow_Alarm’
speed expressed as a % of
Var10
MAX_ANALOG_RPM.
0090
%
Var06
Speed_Shutdown_Alarm_
Setpt %. (See Note
3
).
This is the ‘Red_Alarm’ speed
expressed as a % of
Var10
MAX_ANALOG_RPM.
0080
%
Note 1 : “N.A.” means not applicable to this portion of
Electro-Sentry 1 set-up.
Note 2 : The definition of
Var03
is slightly different when
Var01
is programmed for an analog speed encoder
versus a pulse-train speed encoder.
Note 3 : If you only need to display the speed, without Speed
Alarm Monitoring, then you can skip setting
Var04
and
Var06
. But you then need to set
Var09
to either a
‘0002’ or ‘0003’ as needed per your speed viewing
needs. (More about
Var09
on next page).
