4. Function of relay trigger adapter, analog
4 Function of relay trigger adapter, analog
The relay trigger adapter, analog, ZA 8006-RTA3, provides ALM MO® V6 de-
vices (as of 2008 and except 2390) with a universal trigger output interface
with up to 10 interface elements (i.e. maximum 10 semiconductor relays, or 2
trigger inputs, or up to 4 electrically isolated analog outputs).
The adapter is connected via the ALM MO® cable to output socket A1 to A5 (if
available) on the ALM MO® devices. All 10 interface elements of each module
can be individually selected and configured as ports P0 to P9. Programming is
via the ALM MO® device (for a description please refer to the operating in-
structions for the device) or via its interface (for a description please refer to
the Manual, 6.10.9.2). Addressing of the modules and ports is determined on
the basis of the socket into which the module is plugged (see Man. 6.10.9.2) :
Modules in socket A1 : Address 10 to 19
Modules in socket A2 : Address 20 to 29, etc.
5 Power supply
The adapter is supplied with a voltage of 9 to 12 VDC via the measuring instru-
ment. In the standard version the maximum requirement is 35 mA - even with il-
lumination. It is only with optional analog outputs. in particular with electric cur-
rent outputs, that the maximum supply current on the measuring instrument must
take the sensors into consideration. If the maximum supply current is exceeded,
a mains adapter (e.g. ZA1312-NA1) should be connected at the DC socket.
6 Interface elements
Sockets P0/1 and P2/3 are fitted as standard with four semiconductor relays,
normally open type (or changeover type as option); socket P8/9 is fitted as
standard with two trigger inputs.
Sockets P4/5 and P6/7 can (as options) be fitted with analog outputs.
6 1 Relays
The output relays are driven by the measuring instruments automatically in
the event of alarm or by means of interface commands (see Manual 6.10.10). The
function of each relay can be freely set by configuration (see Manual 6.10.9.2).
The assignment of limit value to relay can be programmed in the sensor by the
device (see Manual 6.10.8). Whenever a relay is activated a programmable mes-
sage appears and whenever there is a change in status a short acoustic alarm
is sounded. The way in which these relays are driven can be configured by
means of inversion so that they pick up in normal conditions and drop out in
the event of alarm or power failure (see below).
In the following cases it is advisable to connect a mains voltage changeover re-
lay downstream (e.g. Phoenix PLC-RSC-24DC/21, 250V 6A) :
► Current or voltage capacity greater than 50 V, 0.5 A
► For separating the mains voltage side
► For implementing an alarm in the event of failure on the control side
4 ALM MO 8006-RTA3

Relays
6 2 Trigger inputs
The trigger inputs TR8 and TR9 can be driven either via optocouplers by volt-
age levels (4 to 30 V) or via the two keys F1 and F2 (configuration, see 6.3.).
When using floating switch contacts the optocouplers must be appropriately
wired with supply U+ and U-
(see diagram).
The trigger function (as standard to start
or stop a measuring operation) can also
be freely configured (see Manual 6.10.9).
6 3 Analog outputs
The relay adapter can also - in various options - be fitted with electrically iso-
lated analog outputs offering the following signals.
Option Output signal Gain
OA 8000-R2 0.000 to +10.000 V 0.5 mV / digit
or 0.000 to +20.000 mA 1 µA / digit
The output value normally corresponds to the measured value for the selected
measuring point. Or alternatively the analog value can be specified as control
variable via the interface (see Manual 6.10.7). The output signal can be pro-
grammed as standard output 0 to 10 V, 0 to 20 mA, 4 to 20 mA for any partial
measuring ranges (see Manual 6.10.7).
6 4 Connecting peripheral equipment
Peripherals can be connected via the supplied ALM MO screw connector ac-
cording to the following schematic diagram :

7 Commissioning
1. Connect the relay adapter to socket A2 on the ALM MO® device; the integrated
interface elements are then available as port P20 to P29.
2. Switch the ALM MO® device ON; see 5.
3. Connect the peripheral equipment to the clamp connectors and on the relay
adapter to the appropriate port sockets; see 6.4.
4. All the following programming functions can be performed via the device
keypad in the "output modules" menu (if available) or using the AMR-Control
software or by means of a terminal command.
Application Summated alarm :
1. For critical measuring points program limit values on the ALM MO® device.
2. With ALM MO® device program the first relay port to variant 0 ´Summated
alarm´ using command ´i20 f9 k0´ (see Manual 6.10.9.2).
3. In the event of any limit value being overshot the associated relay is acti-
vated.
4. If it is intended that the relay should drop out in the event of an alarm it can be
programmed to operate inversely.
Application Monitoring a measuring point :
1. Program the limit value for the critical measuring point xx on the ALM MO® de-
vice.
2. Program relay yy as limit value action (special function) :
Limit value maximum, command : ´Exx ipp f2 Ryy´,
Limit value minimum, command : ´Exx ipp f3 Ryy´,
The relay is configured automatically to the ´assigned´ variant.
3. If it is intended that the relay should drop out in the event of an alarm it can be
programmed to operate inversely.
Application Driving via the interface :
1. With ALM MO® device in the output modules menu program the relay port
pp to variant 8 ´driven´ using command ´ipp f9 k8´.
2. If it is intended that the relay should drop out in the event of activation it can
be programmed to operate inversely - using the command ´ipp f9 k-8´.

Commissioning
3. Activate the relay using the command ´ipp f1 Rpp´,
Deactivate the relay using the command ´ipp f1 R-pp´.
Application Driving the analog output :
1. Configure analog output port 6 or 7; see Manual 6.10.7:
e.g. selected analog type x (command ´ipp f9 Ax´)
assigning to the selected measuring point (command ´ipp f9 E-00´)
or assigning to any reference channel xx (command ´ipp f9 Exx´)
or output the value yyyyy via the interface (command ´ipp f9 ayyyyy´)
2. Define the desired measuring range for the measuring point, to be output
over the whole analog output range (0 to 10 V or 0 to 20 mA), using the pa -
rameters analog start and analog end in sensor programming, special func-
tions, see Manual 6.10.7.
3. If for a current output the output range 4 to 20 mA is to be used (instead of 0
to 20 mA), the element flag for 4 to 20 mA must be activated for the appro-
priate measuring point; see Manual 6.10.3.
