Introduction
EpiSensor’s ZPC Pulse Counter is intended to interface with sensor products which produce either a dry contact
(relay), open collector, or an active voltage pulse output. The ZPC reports the data through the wireless sensor
network to the Gateway.
The ZPC Pulse Counter interfaces with existing meters that provide a pulsed output (gas or water flow, power
consumption, etc.). The ZPC reports data in terms of the ‘number of pulses counted’ and users of 3rd party
software systems can interpret these values and convert to the appropriate Units of Measure for the sensor. The
ZPC-10/12 product variants are battery powered, and the ZPC-20/22 are mains powered versions. The available
product variants are as follows:

Pulse Output Installation
The pulse wires should be fed through the enclosure’s M10 waterproof glands and connected to the terminal
block, taking note of the positive and negative terminals. There will be 2 terminals used per channel, so the
dual-channel pulse counter would use 4 terminals. The pulse input wires are connected to IN1 for single channel
models, and IN1 and IN2 for dual-channel models.

Note: the single-channel pulse counter may use the same hardware as the dual channel version and so would
also have a 4-pin terminal block. However, only the first channel (IN1) will be enabled on the ZPC-10/12 variants.
Dry pulses are not polarity sensitive, but Open Collector and Active pulses are polarity sensitive. Take note of the
positive and negative terminals for both inputs.
Configuring the Jumpers
To the right of the terminal block there is a selector grid that is used to configure the ZPC for different types of
pulse inputs. There are two rows of jumpers in the grid, the top row for IN1 and the bottom for IN2. The columns
of the grid are used to configure the pulse type. For Battery Powered Pulse Counters the selector options are:
●T for Temperature Sensors (Not used on the ZPC product range)
●AP for Active Pulse Inputs
●DP for Dry Pulse Inputs, or Open Collector Inputs
The image below shows a single-channel battery powered pulse counter (ZPC-10) configured for a Dry Pulse
Input. Note that because this is a single channel device, the location of the jumper for Input 2 is not important.

For Mains Powered Pulse Counters the selector options are:
●AP for Active Pulse Inputs
●DP for Dry Pulse Inputs, or Open Collector Inputs
●0-10 for 0-10 Volt Sensors (not used on the ZPC product range)
●4-20 for 4-20 Milliamp Sensors (not used on the ZPC product range)
The image below shows a dual channel mains powered pulse counter where IN1 is configured for a Dry Pulse
and IN2 is configured for an Active Pulse:

Pulse Types
This section describes the operation of the 3 different pulse types.
Page 8of 21
Dry Pulse
A dry pulse can be thought of as a simple switch. Window alarm contacts or reed switches would be examples of
such a connection. In this configuration, a small voltage is applied to the + terminal of the IN connector. A pulse
is detected when this signal is connected to the negative (–) terminal of the IN connector.
The selector grid for Dry Pulse should be on the “DP” setting.
Open Collector Pulse
An Open Collector pulse is generally used by electronic meters. The diagram below is an example of such a Pulse.
Schematic diagram of an open collector pulse output
When the Integrated Circuit (IC) Output is pulsed, the signal on the “Open Collector” gets connected to the IC’s
Ground. This system is polarity sensitive. The Open Collector connection must be connected to the positive (+)
terminal of the IN connector and IC Ground must be connected to the negative (–) terminal of the IN connector.
As the Open Collector is simply an electronic switch, the selector grid for the Open Collector Pulse should be on
the “DP” setting.
Active Pulse
An active pulse occurs when the system generating the pulse applies a positive DC voltage for a short period of
time. This system is polarity sensitive. The Pulse Generator and ZPC units share a common Ground on the
negative (–) terminal of the IN connector. The positive DC voltage representing the pulse must be connected to
the positive (+) terminal of the IN connector.
Note: The Active Pulse Voltage on the ZPC-20/22 should not exceed 40 Volts!
The jumper should be in the “AP” position on the selector grid for monitoring Active Pulse outputs.

Pulse Rate
Depending on the version of ZPC you have, the maximum pulse rate that the ZPC can handle will vary. For mains
powered versions (ZPC-20, ZPC-22) the maximum pulse rate is 40 pulses per second, or 40Hz. For battery
powered versions, the limit is 4Hz.
Pulse Width
The pulse width is the length of time the pulse needs to remain in a changed state to ensure the pulse is
registered on the ZPC.
The minimum pulse width is 10 milliseconds, but this should be configured to a higher value where possible in
the meter or other device that’s generating the pulse. There is no maximum pulse width.
For battery powered pulse counters, the “active state” (closed for dry contacts, or logic high for an active pulse)
should be kept as short as possible. The ZPC will consume battery power while the pulse is in the active state.
Sensors & Settings
Node level settings, sensor level settings and a list of sensors (data feeds) available on the ZPC are listed below.
Data reporting can be enabled or disabled as required for each of the sensors listed.

Radio Power
The power the unit will set for RF
communications. These must be
valid values from the Radio
Manufacturers settings or the radio

If a Power Amp is used, this power
level is amplified further. Care must
be taken not to exceed the regional
variances for max radio power. Both
the Radio Power, and Amplifier
Power must be taken into
consideration when setting this
power level.
