Armstrong Emech G12 User Manual

3.2.5 Temperature Sensor Connector (Port-1)
The Sensor Input and internal electronics are specifically designe
to take the Emech Temperature Probe.
Do not attempt to use any other type of
sensor as this may damage the actuator.
3.2.6 Auxiliary Input (Port-2)
The auxiliary input is set to receive a signal from a
binary switch, usually a flow switch, or a flow sens
such as a paddle wheel ow meter output.
The auxiliary input is a 4 pole M8 male connector that
accepts a 5-24V congurable active low or high signal
to indicate when there is ow.
The 24V output can be used to power the auxiliary
port if required. The current draw MUST NOT EXCEED
100mA.
For auxiliary signal applications Armstrong can supply
a length of cable with a female M8 connector ( Part
Number: MEC0041). The connector will fit the M8 mal
plug found on the underside of the actuator labelled “2”
(see figure 3.8)
The loose end of the cable can be wired to a binary switching device such as a flow switch, flow sens , level switch,
manual switch or used with a PLC. Switching will enable various features of the Emech G1 actuator such as BIGAIN,
STANDBY, HOLD, and INVERSE ACTUATOR OPERATION. These features are outlines on the following page and the
actuator software configuration are listed in section 5.3.3
This input can be used in conjunction with the G1 actuator’s automatic gain switching feature to allow the actuator to
respond appropriately in applications where flow is variable or intermittent
Figure 3.9 represents the actuator
mounted male plug (Port-2) found on the
underside of the actuator (see image 1).
The colors indicated in Figure 3.10 are
the wire colors of the matching cable and
connector auxiliary input cable.
The switching device should be placed
between Pin 1 ‘oV’ BLUE and Pin 3 ‘FLOW’
WHITE.
