2 Description
2.1 Function
The device measures the speed of rotating equipment such as turbines, compressors or ex-
panders and monitors it versus setpoints and converts it into an analog output.
Parameters may be set via front keyboard and display or via the USB2.0 data interface.

Note: E16521D.4 does not have LEDs, keys and display.
2.3 Display
During normal operation, the speed will be displayed.
2.4 Status LEDs
LEDs 1 to 4 are on if the corresponding output relays OR1 to OR4 are energized.

Checksum will be shown in a scrolled display (as long as is pressed).

2.7 Event Codes on Display

SE-01 : Sensor fault or signal lead break
2.8 Measuring Principle
Measurement is based on the frequency of the pulse sequence representing the speed. Basic
quantity is the time between one or more of its pulses. An automatic function determines this
number, in order to maintain a minimum period of time for every measurement to be extended
over. This time minimum is programmable to 5 milliseconds or more, thus establishing a corres-
ponding averaging and stabilization of measurements.
The corresponding speed value in terms of RPM, by which the display, the alarms and the
analog output are reading, computes from these measurements. This process further considers
the programmed application data (relation between machine speed and signal frequency).
2.9 Performance at Signal Break
In normal operation, the function closely tracks the input sequence, with the programmed
performance. After a sudden interrupt of the input pulses, the unit reduces the readings following
an automatic step-down sequence. This starts as fast as the most recent measuring sequence
before interrupt but then decreases slower and slower (reciprocal) until it meets the programmed
low end.
2.10 Input Starter
As long as the input Starter is true, the enabled setpoints will be put to their assigned relay state.
Note:
A positive edge at the input Starter will reset latched alarms.
2.11 Input Reset
A positive edge at the input Reset will reset latched alarms.
The input Reset must be actuated once after power up of the Monitor (if parameter P01.07 = 0).
if:
•power has failed and returns at speed < SP2 and input Starter is still true
•power has failed and returns at speed > SP2 and input Starter is still true or not true
2.12 Setpoint SP1 with Safety Output OR1
SP1 has individually programmable response characteristics.
OR1 has two SPDT relays connected in series.
OR1 can be programmed to respond also to SP2.
2.13 Setpoints SP2 with OR2, SP3 with OR3, SP4 with OR4
Each with individually programmable response characteristics, and each with programmable
starter.

E16521D-Manual_EN_Rev12 2021_JAN_14 Page 8 of 26
2.14 Analog Output
Output signal isolated and linear as current 0/4…20 mamps into 500 Ohms max load.
Live zero as well as high and low end of conversion programmable.
2.15 Pulse Repeating Output
Push/pull with approx. 20 volts level, isolated versus signal input and versus power supply.
Repeating the input pulse signals by the same sequence.
2.16 Response Time of Safety Output OR1 to Trip Condition
The response time of the Safety Output OR1 to Trip Condition is less than 15 ms (at a minimum
measurement time of 5 milliseconds).

P00.03
Minimum Measuring Period
in milliseconds
Range: 0005 .. 9999
The measurement is based on a time interval measurement over a (variable)
number of input signal pulses. A programmable minimum measuring period
thus will be maintained, automatically including more input pulses into every
measurement with increasing input frequency. This establishes an averaging
over the programmed period of time, which helps to stabilize the
measurements, specifically with fluctuating variables. The setting of P00.03
defines the minimum measuring period of time, in terms of milliseconds,
within a range of 0005....9999 milliseconds. A setting less than 0005 is
possible, but minimum measuring time will still be 5 msec.
P00.04
Starter Time Period
Range: 000 .. 999
This step sets the starter time period (duration) in terms of seconds. The
starter condition state lasts from the beginning of the external starter signal
plus the programmed time elapse following its end. Valid for all setpoints with
the activated starter.

P01.01 and P01.03:
Scaling
Scaling defines the relation between the input signal frequency (in terms of
Hz), and the corresponding display (e.g. in RPM and decimal position
required by the application). Both values are freely programmable by their
decimals and numerical amount. Of course, they must refer to the same
operation level. This reference point is recommended close to the high end of
the intended operation range. In later operation, however, it may be overrun
without error.
Example:
A rotating shaft to be measured carries 36 slots. At a shaft speed of 1500
RPM, this produces a signal frequency of 1500 × 36 pulses per minute =
54,000 pulses per minute = 54,000 ÷ 60 Hz = 900 Hz. (Presuming the predi-
vider is set to 001).
Therefore, 900 (Hz) and 1500 (m/min) are the data-set to be programmed in
the corresponding program steps:
Step P01.01 : parameter = 00900
P01.03 : parameter = 01500.

If the speed falls lower than this level, the measurement will be canceled to
zero even if the machine still turns with a speed lower than 1 RPM (at value
of 00001).
