Preventing burns and fire
•The fog produced by the machine is hot enough to cause burns when it
leaves the nozzle, and very hot droplets of fluid escape occasionally.
Keep people and objects at least 600 mm (24 in.) away from the fog
output nozzle.
•Do not touch the fog output nozzle during or after use – it becomes
extremely hot and remains hot for several hours after the machine has
been shut down.
•Fog output contains glycol, a flammable alcohol that burns with an
almost invisible blue flame. Do not point fog output at sources of ignition
such as open flames or pyrotechnic effects.
•Do not attempt to bypass thermostatic switches, fluid sensors or fuses.
•Replace fuses only with ones of the type and rating specified in this
manual for the machine.
•Provide a minimum free space of 100 mm (4 in.) around the machine.
•Provide a minimum free space of 500 mm (20 in.) around fans and air
vents and ensure free and unobstructed airflow to and around the
machine.
•Keep the machine at least 600 mm (24 in.) away from combustible and
heat-sensitive materials.
•Do not operate the machine if the ambient temperature (Ta) is below 5°
C (41° F) or above 40° C (104° F).
•Do not operate the machine if the relative air humidity exceeds 80%.
Preventing injuries
•Fasten the machine securely to a fixed surface or structure when in use.

will be underneath. Use only the hanging bracket to suspend the machine.
Ensure that there is at least 100 mm (4 in.) clearance all-round the machine and
at least 600 mm (24 in.) in front of the fog output.
The machine is delivered with white nylon shipping bolts fitted to the
hanging bracket in place of the normal hand-wheel bolts. Before first
use, remove the shipping bolts and replace them with the hand-wheel
bolts (outside of bracket) and spacers (inside of bracket) which are
supplied separately in the packaging.
AC power
Before using the machine, ensure that a grounding-type (earthed) power plug
that fits the local power receptacle is installed on the power cable provided.
DANGER! Make sure the power plug is correctly rated:
•For EU ZR25, ZR35, ZR45 models use a plug rated at 10 A minimum.
•For US ZR25 use a plug rated at 10 A minimum.
•For US ZR35 use a plug rated at 15 A minimum.
•For US ZR45 use a plug rated at 20 A minimum.
When installing the plug, follow the plug manufacturer’s instructions and
connect pins as follows:
Yellow and green wire to ground (earth), blue wire to neutral and brown wire to
live.
The table below shows some common pin identification schemes.
wire function marking screw colour
brown live “L” yellow or brass
blue neutral “N” silver
green/yellow earth green

Before connecting the machine to power, verify that the AC supply is adequately
dimensioned for the current draw of the machine.
1200W 240V EU / 1000W 120V US
1550W 240V EU / 1450W 120V US
2100W 240V EU / 1800W 120V US
Check that the local AC voltage is appropriate, as indicated on the machine’s
serial number label. If your AC voltage is outside the appropriate range, do not
use the machine. Contact Martin Service and Support for assistance.
Setting up
Fill the fluid reservoir with an approved Martin fog fluid as shown on page 22. If
DMX control is being used, connect the machine to the DMX line (see page 19).
If you are using several machines from one control panel in host-client link
mode, link the machines in a daisy chain using the DMX in and out sockets. It
does not matter which socket is used as input or output.
Final checks
Before applying power to the machine, verify the following:
•the machine is safely located or installed and meets the location
requirements stated on page 13
•the operator is familiar with, and able to comply with, the requirements
for safe operation listed on page 5.
•the fluid is one of the approved Martin fluids listed under “Approved Fog
Fluid types” on page 22.
•the machine is electrically grounded (earthed)

DMX control
DMX control
Overview
DMX is a digital control protocol widely used in entertainment and architectural
lighting. Any DMX controller meeting the DMX-512A standard, may be used to
control the machine. A controller that is RDM compliant will be able to program
and monitor some settings of the machine remotely.
When a DMX signal is present, the machine’s stand-alone functions
do not work. To control the machine locally the DMX controller must
be powered off or disconnected.
If the DMX signal is removed (controller turned off or unplugged), the
machine will revert to its previously stored RUN MODE settings.
If the machine was set to OFF, it will revert to this state.
If the machine was set to STANDBY, it will revert to this state.
If the machine was set to TIMER, it will revert to this state.
If the machine was set to CONTINUOUS, it will revert to this state.
Connection
The JEM ZR series machine provides 5-pin XLR connectors on the rear of the
machine for DMX connection.
For best results, use cable designed for high speed digital data transmission.
DMX functions
The JEM ZR series DMX start address must match the DMX start address
assigned to it on your controller. To set the address, see “Setting the DMX start
address” on page 16. The machine has two DMX personalities, requiring one or
two DMX channels. The mode is set using the two RECEIVE options in the LINK
menu, or via RDM. (Prior to firmware 1v4, only 1 channel was used.)
When the machine is at running temperature and is under DMX control it
displays DMX (+ the current DMX base address).
The DMX control values are shown in the table below.

Setting options by RDM
You can remotely configure the fixture over DMX using RDM. Martin offers a
range of suitable RDM-compatible controllers.
A full list of the RDM functions that the machine supports, is given at the end of
this section. These functions are generally referred to, using the more specific
term ‘PIDs’ or ‘Parameter IDs’.
Scanning for RDM devices on the data link
Before you can communicate with fixtures using RDM, you must send a scan
command (also called a device discovery command) to all the devices on the
data link so that the RDM controller can identify them. It does this by retrieving
each device’s factory-set unique identifier (UID). This process can take some
time depending on the number of devices on the link.
To identify the fixtures on the link:
1. Check that the fixtures are correctly connected to the RDM controller
on the data link and that power is applied to all fixtures.
2. Give the controller time to identify the devices on the link and prepare
for communication with the devices.
Getting status and setting options by RDM
The status and options listed in the table below can be read and set by RDM.
You can set an option on one fixture by sending a unicast RDM command to
that one fixture only, or you can set the same option on all the fixtures on the
data link by sending a broadcast RDM command to all the devices on the link.
For status reading, you can only use unicast RDM to read information from an
individual fixture.
