Coat-Endure User Manual & Datasheet V 3.0
1 Introduction
Coat-Endure is a microcontroller based compact coat im-
mune admittance level limit switch. It is a compact level
switch which is suitable for sticky solids, pastes and slur-
ries. The device is specially suited for compact silos and
packaging machines where material has a tendency to stick
on the probe.
Figure 1: Coat-Endure
2 Operating Principle
Coat-Endure is an improvement over traditional principle
of admittance. The ring type probe has an alternating active
and an inactive region, which collectively help the controller
to calculate the extent of coating on the probe. In effect,
the device is able to identify the differential coating between
the sense and the shield by measuring their individual ca-
pacitances. As the coating immunity is controlled by the on-
board microcontroller, the extent of coating immunity can be
set easily.

8 Installation Guidelines
While installing the instrument, please take care of the
following points:
1. The instrument should be installed in horizontal or ver-
tical position only.
Material Inlet Source
Figure 3: Proper Mounting Arrangement
2. Observe that when installed directly under the mate-
rial inlet source, a canopy called baffle of appropriate
strength and size should be welded right above the in-
strument as shown.
Material Inlet Source
Baffle
Figure 4: Coat-Endure with Baffle
3. To prevent the ingress of moisture and water seepage
in side mounting position, the cable entries should al-
ways point downwards.
Figure 5: Cable Gland Arrangement
4. Secure the cover of housing tightly. Tighten the cable
glands.
5. Make all electrical connections as instructed in the
manual. Don’t power on the device before verifying
the connections.
6. Weatherproofness of enclosure is guaranteed only if
the cover is in place glands adequately tightened.
Damage due to accidental entry of water can be
avoided if the instrument is installed in a rain shade.
7. If the ambient temperature is high, the instrument
should not be installed to receive direct sunlight. In
case such a position of shade is not available, a heat
shield should be fitted above the instrument especially
if the operating temperature lies between 60◦C and
80◦C.
9 Electrical Connections
Electrical connections for the instrument will change with
the models. Please refer to figure 6 and the precautions
mentioned below before connecting the device.
Precautions for connecting Coat-Endure :
•Power Supply Rating
Make sure the power supplied to the instrument is
within the specified range mentioned in Table 1.
•Connect Earth
When supplying AC power, please make sure that the
grounding screw on the housing and the earth terminal
are all connected to the plant’s earth.
•Power Supply Fluctuations & Noise
External noise or fluctuating power supplies could af-
fect performance and shorten the life of the instrument.
Use external line suppressors and fuse wires to con-
tain the risk of damage to the circuit.

10 Calibration
The DIP switches for calibration can be accessed by
opening the top aluminium cover. Calibration process
depends on the conductivity of the application material.
10.1 Calibration for Non-conductive Material
Note: Calibration in air is specific to the tank, if the
tank changes, the instrument needs to be calibrated
again.
This calibration is also known as Air Calibration and Cali-
bration without material. It should be done without the ap-
plication material (i.e only air, no material). Once calibrated
in the empty tank, the device can be used with a wide range
of materials. Calibrating the instrument outside the tank can
cause malfunctions.
Calibration in empty
tank(without material)
Figure 7: Calibration for Non-conductive Material
Follow the procedure given below to calibration the
sensor:
•Install Coat-Endure in an empty tank.
•Unscrew the cover and ensure that all DIP switches
are in the OPEN position as shown in Figure 8. Make
sure that the status LED is not blinking for error.

10.2 Calibration for Conductive Material
For applications using conductive materials (water, acid
based pastes etc.), Coat-Endure needs to be calibrated with
the application material. This will make the instrument spe-
cific to the application material i.e. if the application material
is changed; calibration should be repeated.
Figure 12: Calibration for Conductive Material
Follow the procedure given below to calibration the
sensor:
•Fill the tank with the application material such that the
Coat-Endure’s probe is completely covered with the
material.
•Unscrew the cover and make sure that all DIP switches
are in the OPEN position as shown in Figure 8. Ensure
that the STATUS LED is not blinking for error.
•To start with the calibration, set the HI CALIBRATE
switch to CLOSE (Opposite of OPEN for DIP switch)
position as shown in Figure13 and wait until Green
LED becomes stable.

11 Cover Delay
Note: Set the value of Cover Delay between 1-25 secs.
When the application material covers the probe, the
changeover of the output can be delayed by a pre-
determined time. This time is called Cover Delay. For a
different value of cover delay, the number of blinks can be
adjusted as per requirement. Follow the procedure given
below for setting cover delay:
1. Ensure that all DIP switches are in OPEN position as
shown in Figure 16. Make sure that STATUS LED is
not blinking for error.
2. Set the COVER switch to CLOSE (Opposite of OPEN
in a DIP switch) position as shown in Figure 17.
3. Press ENTER. The STATUS LED for RELAY 1 starts
blinking. Blink the STATUS LED according to value of
cover delay.

5. To test, dip Coat-Endure into the application material
until the switching point is reached.
6. The STATUS LED will start blinking RED if the switch
point is reached. It will blink for the number of seconds
for which the cover delay is set. 1 blink is equal to 1
second during switching.
12 Uncover Delay
Note: Set the value of Uncover Delay between 1-25
secs.
When the application material uncovers Coat-Endure’s
probe, the changeover of the output can be delayed by a
pre-determined time. This time is called Uncover Delay. For
a different value of uncover delay, the number of blinks can
be adjusted as per requirement. Follow the below proce-
dure for setting uncover delay:

1. Ensure that all DIP switches are in OPEN position as
shown in Figure 16. Make sure that STATUS LED is
not blinking for error.
2. Set the UNCOVER switch to CLOSE (Opposite of
OPEN in a DIP switch) position as shown in Figure 20.

5. To test, dip Coat-Endure into the application material
until the switching point is achieved.

switch point is achieved. It will blink for the number
of seconds for which the Uncover Delay is set.
13 Sensitivity
Note: Set the sensitivity value between 1-5.
Sensitivity of the level sensor may have to be adjusted de-
pending on the dielectric constant of the application media.
Coat-Endure has a LED bar display which helps in visual-
izing the desired sensitivity level. The device ships with a
default sensitivity level of 3.
Traverse the following steps to set the sensitivity of
Coat-Endure:
1. Set the UNCOVER and CALIBRATE switch to CLOSE
position.

3. To modify the set value, Press ENTER and HOLD the
key, RED Status LED for RELAY 1 will start blinking.
Count the number of times the LED blinks and release
the ENTER key after the required value. e.g. For set-
ting the sensitvity to 4, count up to four blinks and re-
lease the ENTER key.

14 Failsafe
In a condition of device failure, known errors and input
power failure the outputs of the device resemble the ALARM
condition. This is meant to prevent overflow or dry run con-
ditions in case of failures.
Prevent Overflow - High Level Switch: Failsafe High
(default) is set by moving the FS 1 and FS 2 switch for RE-
LAY 1 and 2 to OPEN position.
1. When not in contact with the material, LED turns
GREEN.
2. When in contact with the material, LED turns RED.

Use of LED Bar Display: The bar display can be used
for two purpose:
•Sensitivity: Refer to section Sensitivity for more details.
•Display Mode: The display mode shows the material
distance from the instrument’s probe. The movement
of LEDs in upward direction depicts the movement of
application media towards Coat-Endure’s Probe and
vice-versa, as shown in Figure 29.

17 Output Options
Depending on the selection mode for output, the two re-
lay outputs can also operate independantly for two different
switch points. Refer to Order Code
•All keys should be in the OPEN position.
•To see the output mode, press and hold ENTER key.
•If the only the first LED lights up, Coat-Endure is oper-
ating in the single point switching mode.
18 Error Indication
On error, the status LED starts blinking RED and GREEN
alternately at a faster rate. Normal LED blinks are always
at the rate of 1 blink per second, in either RED or GREEN
color. In some cases, a GREEN or a RED blinking could
