Figure 2. Terminal Blocks for Signal Inputs, Voltage Outputs and Serial Communication
Digital Inputs (1)
Chatter has four digital inputs each with four functions during normal operation:
NC (passive) The input is normally connected to GND and will be
activated, when the connection is broken.
NO (passive) The input is normally open and will be activated, when it
is connected to GND.
NC (active) The input is normally connected to a voltage between 2 - 5V
and will be activated, when the connection is broken.
NO (active) The input is normally open and will be activated, when it is
connected to a voltage betweeen 2 - 5V.

Battery (6)
The battery is located on top of the Chatter PCB (see Figure 3). Connec-
tion is through a connector placed in the middle of the circuit board (“Bat-
tery”, red and black wires).
Please note that the battery can be replaced without first setting the Chat-
ter unit in ”OFF” position.
See section 6. Gain Access to SIM Card and Battery and section 7.
Internal Installation in the Chatter Unit for gaining access to and chang-
ing the battery.
Jumper (7)
A jumper is placed right below the battery with two positions: ON and
OFF. In ON position the Chatter incl. pressure transmitter is powered (acti-
vated), and in OFF position it is disconnected (switched off).
Booster Capacitor (8)
The booster capacitor delivers current during data transmissions.
SIM Card (9)
The SIM card facilitate communication via the GSM/GPRS network.
See also the procedure for inserting/changing the SIM card in section
7. Internal Installation in the Chatter Unit on page 25.

5. Mounting
MJK Chatter data logger is supplied in two different mounting versions: one
for pipe mounting and one for wall mounting (mounting on wall or cabinet).
5.1 Pipe Mounting
Necessary tools and parts:
• Wedge set to fit pipe diameter
• Socket spanner, 7 mm
1. Activate the Chatter unit(s) as described in section 9. Physical Activation
on page 31.
2. Re-assemble the Chatter unit(s) as described in section
6.2 Wall Mounting on page 23.
3. Prepare the Chatter base with wedges to fit the pipe diameter:
Wedge From inner diameter ----> to inner diameter
Wedge 1 Ø63 mm Ø71 mm
Wedge 2 Ø70 mm Ø78 mm
Wedge 3 Ø77 mm Ø85 mm
Wedge 4 Ø84 mm Ø92 mm
Wedge 5 Ø91 mm Ø99 mm
Wedge 6 Ø98 mm Ø106 mm

4. Secure stud bolts and wedges with a rubber band as shown below.
3.
4.
Figure 4. Secure Stud Bolts and Wedges with a Rubber Band
5. Immerse the Chatter base in the pipe (if possible with the padlock point-
ing away from public view), and then pull the screws up until the wedges
buckle in the pipe. Thereby the base is centered in the pipe, and the
wedges will automatically level.
5.
Figure 5. Center the Base
6. Screw the screws into the base, one by one without using any tool:
6.
Figure 6. Screw by Hand
Data Logger
16EN 6.10 Chatter Hardware Manual 1511

7. Tighten the screws with a 7 mm spanner until the base is bolted onto the
pipe:
7.
Figure 7. Tighten the Screws with a Spanner
From here on the base may not be moved, rotated or lifted!
8. Fasten the security wire of the pressure transmitter into the base before
the pressure transmitter is placed inside the pipe.
IMPORTANT: Use a large washer between the wire and the screw, so
that the wire can not escape the base!
8.

9. Remove the protective sleeving from the pressure transmitter and immerse
the pressure transmitter in the pipe.

Figure 9. Immerse the Pressure Transmitter
10. Connect the pressure transmitter cable to the green Chatter top.
IMPORTANT: The guide pins must align to ensure correct
connection.

11. Mount the Chatter top on the base by turning the top approx. 1 cm
counter-clockwise, until the holes for the security padlock align.
Expect a slight drag over the last few millimeters. This is due to the activa-
tion of the intruder alarm (a magnetic switch between top and base).
12. Mount the padlock (see figure below).
