Inputs/Outputs:
Detector terminal: (2a/2c)
II 2 G [EEx ib] IIC or II 2 G [EEx ib] IIB
The table below shows the highest permissible external
inductivity and capacity:
II 2 G [EEx ib] IIC II 2 G [EEx ib] IIB
Highest per-
missible ex-
ternal induc-
tivity
0.15 mH 1.8 mH
Highest per-

ternal capac-
ity
344 nF 507 nF
The effective inner inductivity is negligible.
Effective inner capacity: 12 nF
For inherently safe installation, the cable ends on the
strip terminal must be protected by a 10 mm long
shrink-down plastic tubing (see also the connection
diagram)
3 digital inputs: passive
1. Belt stop or erase mass integrator (18a/18c)
2. External start tare measurement or print start,
Product 3+4 and Start/Stop and print (20a/20c)
3. External product selection (22a/22c)
